You can overlay the image layer with the DEM layer. The following is the name and description of the function: DataSource: The data source where the DEM data is superimposed on the image. Dataset: The name of the DEM dataset displayed superimposed on the image. Azimuth: Azimuth of the light source. The direction used to determine the light source is from the north-north direction of the position of the light source to the angle between the light source and the target direction line in a clockwise direction, ranging from 0-360 degrees to 0 degrees in the north direction, in a clockwise direction Increment. The default is: 315. Altitude: The height angle of the light source. The angle of inclination used to determine the illumination of the source is the angle between the direction line of the source and the target and the horizontal plane, ranging from 0 to 90 degrees. When the height angle of the light source is 90 degrees, the light source is perpendicular to the surface. The default is: 45. ShadowModel: The rendering type of the 3D shading map. There are three values: 1 for the local illumination angle and the effect of the shadow. ; 2 means that only the local illumination angle is considered; 3 means that only the area is considered to be in the shadow. The default is: 2. ZFactor: Elevation scaling factor. This value is the unit transform coefficient of the raster value (Z coordinate, or elevation value) relative to the X and Y coordinates in the DEM raster. Usually, in the calculations in which X, Y, and Z are involved, the elevation value needs to be multiplied by an elevation scaling factor so that the three units are consistent. For example, the unit in the X and Y directions is meters, and the unit in the Z direction is feet. Since 1 foot is equal to 0.3048 meters, you need to specify a scaling factor of 0.3048. If set to 1.0, it means no scaling. The default is: 1.

A slope map is generated for the DEM raster data. The following is the name and description of the function: Altitude: The height angle of the light source. The angle of inclination used to determine the illumination of the source is the angle between the direction line of the source and the target and the horizontal plane, ranging from 0 to 90 degrees. When the height angle of the light source is 90 degrees, the light source is perpendicular to the surface. The default is: 90. ZFactor: Elevation scaling factor. This value is the unit transform coefficient of the raster value (Z coordinate, or elevation value) relative to the X and Y coordinates in the DEM raster. Usually, in the calculations in which X, Y, and Z are involved, the elevation value needs to be multiplied by an elevation scaling factor so that the three units are consistent. For example, the unit in the X and Y directions is meters, and the unit in the Z direction is feet. Since 1 foot is equal to 0.3048 meters, you need to specify a scaling factor of 0.3048.

Viewshed: Specifies the value re-assigned by the visible domain. The default value is 0. NoViewshed: Specifies the value of the image, which is the value given by the non-visual domain image area. StartAngle: The specified starting observation angle set, one-to-one correspondence with the observation point. The unit is degree, which is 0 degrees in the north direction and rotates clockwise. Specifying a negative value or greater than 360 degrees will automatically convert to a range of 0 to 360 degrees. The default is: 0. ViewAngle: The specified set of observation angles corresponds to the observation point and the initial observation angle. The unit is degree and the maximum value is 360 degrees. The observation angle is based on the starting angle, that is, the viewing angle range is [starting angle, starting angle + viewing angle]. For example, the starting angle is 90 degrees and the viewing angle is 90 degrees, so the actual angle of observation is from 90 degrees to 180 degrees. Note, however, that when a value of 0 or a negative value is specified, the observation range is 0 to 360 degrees regardless of the starting angle. The default is: 0. ViewRadius: The specified set of observation radius, one-to-one correspondence with the observation point. This value limits the size of the field of view. When the observation radius is less than or equal to 0, it means no limit. The unit is meters. The default is: -1.

The image stretch type. Now it supports the No-stretch, Standard Deviation Stretch, Max and Min Stretch.

No-stretch. No-stretch is to process the image data without any stretch, which is only valid for image data in the 8-bit unsigned integer type. The pixel value of image data displayed on the computer are from 0 to 255. Hence for image data in the 8-bit unsigned integer type, after the No-stretch process, all of them will be linear stretched and whose value will be converted into [0, 255]. When the image data uses the 8-bit unsigned integer type for storage, SuperMap uses the Max and Min Stretch for display, so for the 8-bit unsigned integer type, the display effect of No-stretch is consistent with that of the Max and Min Stretch.

Standard Deviation Stretch. This method performs statistics on the original image data, which is mainly to get the value range of a standard deviation, then to recalculate the range of the standard deviation according to its stretch coefficient, and ultimately to do the linear stretch for the last calculated range of standard deviation to make its values distribute within [0,255].

Max and Min Stretch Max and Min Stretch is a linear stretch, based on the maximum and minimum pixel values which will be considered as two endpoints of the stretched histograms. For example, an image is in 8-bit storage type and the range of its pixel values are from 30 to 200, then after Max and Min Stretch, the pixel values of the image will be redistributed and the new range is from 0 to 255. With this stretch method, contrast and brightness of the image are improved significantly so that the features in the image will be more easily identified.As shown in the figure below, the left figure is the one before the stretch, the image is dimmer, and the display values of pixels are concentrated in the lower grayscale region. While after Max and Min Stretch, the image becomes clearer and its contrast becomes greater.

Histogram equalization. Histogram equalization is to is for the non-linear stretch, and redistribute the image pixel. It will make the number of pixel in a certain gray range same.

Histogram match. Histogram match is to conduct the mathematical manipulation for the image search table, which make a histogram of the image is the same as another histogram of the image.

Gaussian stretch. The purpose of Gaussian Stretch is to make pixel values of image data tend to the normal distribution. If Using Median is selected, then Gaussion stretch would be performed with the median of cell value as center. If not selected, then Gaussion stretch would be performed with the maximum of cell value as center.

Percentage truncated stretch. In this type of stretching, some pixels in a small part and some pixels in a large part in the histogram are removed from the stretch. This method of stretching requires specifying the minimum and maximum percentage values excluded from the drawing, respectively represent the percentages of the minimum and maximum pixels that need to be excluded from the stretch.As shown in the figure below, the first picture shows the maximum value of the image display and histogram. The second picture below shows the effect of the image cut through the percentage.

Portable Network Graphics (PNG) PNG is a format that exceeds GIF format and offers a lot of functions. The info is not compressed. PNG file can store the color with 8 24 or 48 bits every pixel and store the gray degree with 1 2 4 8 or 16 bits every pixel. Compared to the GIF file ,it can be only with 1 2 4 of 8 bits for every pixel. PNG file has a alpha value which indicates the how the color of the pixel mixes with the background color.One of the advantages of PNG comparing to GIF is: it can display a image progressively. PNG file has info of gray and color correction that makes it display in the varies of devices precisely.

Graphics Interchange Format (GIF) GIF. GIF is a common format to display the image in the web page. It is suitable for the drawing line, image with pure color or clear boundaries. It is compressed but without info loss.One color in the GIF file could be defined the transparent, so the image will display the background of its any web pages. Storing a series of GIF file in a file can form a animation. GIF file can store 8 bits at most for each pixel. The color of GIF is limited to 256.

JPG. JPEG is a compressed scheme with some info loss which is hardly sensed by eyes. Over 16 million color is supported by JPEG due to the 24 bits storage .JPEG don't support transparent and animation and is not a file format while “JPEG file exchange format (JFIF)” is a format, which is usually used to store and transfer the image compressed by JPEG scheme.The suffix of JFIF file is .jpg in web browser.

The BMP type.BMP. BMP is a standard format to store the image used by windows. The ever pixel bit value (1, 4, 8, 15, 24, 32 or 64) of the specified BMP field is set in the head of the field.The each pixel of 24 bit is general use.And BMP is not compressed, hence it is not suitable for Internet transmission.

Tag Image File Format (TIFF)TIFF is an expendable format for all kings of platform and applications. All kinds of compression scheme can be used for TIFF. Several images can be stored in a single, multiple-page TIFF file. Information related to the image (scanner maker, host computer, type of compression, orientation, samples per pixel, etc.) can be stored in the file and arranged through the use of tags. You can extent the TIFF format by granting and adding the new tags.

ESP.EPS. EPS, Encapsulated PostScript, is a standard cross-platform format. The suffix on PC platform is .eps, while on Macintosh platform is .epsf. It is used for the storage of vector image and raster image.

EMF. EMF. EMF, a file format in Windows in printing industry. It is the 32 bits version of WMF(Window metafile). The produce of EMF is to deal with the shortcomings in the printing industry.

The source event.A PointInputEventArgs that contains the event data.

Specifies the constants that define the methods used to create ranges.In Ranges Map, a field or an expression, which is regarded as the thematic variable, can be separated into several ranges according to a certain range method. Each feature or record is separated into a certain range in terms of the thematic variable. The features or records in the same range have the same display style. Generally, Ranges Map is used to display the characteristic (like the amount or the degree) of continuous phenomenon, such as the distribution of rainfall, the distribution of soil erosion intensity. Ranges Map reflects the distributing differences of phenomenon's developing standard or intense degree in each area.

Users specify an interval to divide the thematic variable. The number of ranges is determined by the user-defined interval and the maximum and the minimum of the thematic variable. The break value can be calculated by the following formulaVi is the break value; Vmin is the minimum of the thematic variable; d is the user-defined interval; count is the number of ranges; i is the positive integer from 0 to count minus 1 and represents each range; when i is 0, Vi is Vmin; when i is count minus 1, Vi is Vmax.

Equal Count. Make sure each range contains equal number of object. The number is determined by the number of ranges and the number of features, the number of objects in each range will be the same if the number of the features be divided with no remainder by the number of the ranges, otherwise the ranges in the rear will have one more object than the ranges in the front. For example, there are 9 objects and need to be divided into 9 ranges, each range will has one object, if divided into 8 ranges, the eighth range will has two objects. This kind of Dividing applies to linear data. The feature numbers in each range can be calculated by the following equation:Where, n is the number of features in each range; N is the total number of the features; count is the number of user-defined ranges. If n is a decimal, it will be floored.

Actually, Logarithm range method is performing the Equal interval range method for the logarithm of the original data, with 10 as the base. First, acquires the break value of the logarithm of the original data using the method of Equal interval, and then performs power function for each break value, with 10 as the base and these break value as exponent, to get the break value of the original data. This method is more suitable when the maximum and the minimum of the thematic value is large, and the Equal interval range method is not so good. Logarithm range method can reduce the differences of the data, and its compression ratio is higher than Square root range method. The interval can be calculated by the following formula:Where, d is the interval; Vmax is the maximum value of thematic variable; Vmin is the minimum value of thematic variable; count is the number of user-defined ranges. The break value can be calculated by the following formula:Where, Vi is the break value; i is the positive integer from 0 to count minus 1 represents each range. When i is 0, Vi is Vmin; when i is count minus 1, Vi is Vmax.Note: This method is not available for negative.

Standard deviation range method represents the difference between the value of the thematic variable and the mean value of the thematic variable. The first step of this method is to calculate the mean value and the standard deviation of the thematic variable. The length of each range is a standard deviation, and the middle one is such a range that the center is the mean value and the length is a standard deviation. If the mean value of the thematic variable is mean, and the standard deviation is std, the range will be like the follows:For example, the thematic variable is the value from 1 to 100 and the mean value of the thematic variable is 50, and standard deviation is 20. Performs this method the range will be 40-60, 20-40, 60-80, 0-20, 80-100. The features in different ranges have different display styles.Note: users can not set the number of ranges. The number of ranges depends on the data itself.

Virtually, square root range method is performing the equal interval range method for the square root of the original data. First, calculates the break value of the square root of the original data using the method of equal interval, and then performs square function for each break value to get the break value of the original data. So in this method, it is possible that there is no value in certain ranges, namely the feature or the record in the ranges is 0. This method is better than the equal interval range method when the difference between maximum and the minimum of the thematic value is large. This method can reduce the differences of data, and separate the data into less number of ranges. The interval can be calculated by the following formula:Where, d is the interval; Vmax is the maximum value of thematic variable; Vmin is the minimum value of thematic variable; count is the number of user-defined ranges. The break value can be calculated by the following formula:Where,Vi is the break value; i is the positive integer from 0 to count minus 1, represents each range. When i is 0,Vi is Vmin; When i is count minus 1, Vi is Vmax. Note: this method is not available for negative.Note: This method is not available for negative.

Equal interval range method uses the maximum and the minimum of the thematic variable and the number of ranges defined by users to create equal-sized range. Each range has the same length. The interval can be calculated by the following formula:Where, d is the interval; Vmax is the maximum value of thematic variable; Vmin is the minimum value of thematic variable; count is the number of user-defined ranges. The break value can be calculated by the following formula:Where,Vi is the break value; i is the positive integer from 0 to count minus1, represents each range. When i is 0, Vi is Vmin; when i is count minus 1, Vi is Vmax.For example, the value of a thematic variable is from 1 to 10, you want to use this method to separate it into 4 ranges. The result will be 1-2.5, 2.5-5, 5-7.5 and 7.5-10 (the break value belongs to the next range).Note: Using this method, it is possible that there is no value in certain ranges, namely the feature or the record in the ranges is 0.

The graduated symbols map.The graduated symbol map uses the size of a symbol to represent the thematic values of features. When the features are rendered using graduated symbols, the values of thematic variables are grouped into ranges, and the features whose thematic values are within one of the ranges will be rendered with the symbol of the same size. The thematic variable used to create the graduated symbol map should be of numerical type.

The graph map.In a graph map, a graph is drawn for every feature or record to show the thematic value of it, and the graph map allows you to examine more than one variable per feature at a time, for example, in a column graph map, you can draw several columns in a column chart each shows the value of a thematic variable. The following types of graph map are supported: area chart map, step chart map, line chart map, scatter chart map, column chart map, 3D column chart map, pie chart map, 3D pie chart map, rose chart map, 3D rose chart map, stacked column chart map and 3D stacked column chart map.

The dot density map.The dot density map uses the count and intensity of points to represent the thematic value of a region or area, in which, one point represents a specified number of something like population, number of subbranches, etc., which is the thematic variable, and the number of the points in a area multiplied by how many a point represents equals the thematic value of the area. The closer together the points are, the higher the density of phenomenon the thematic variable denotes are. The thematic variable used to create the dot density map should be of numerical type.

The ranges map.In a ranges map, the features or records are grouped into multiple ranges according to the values of the thematic variable, and features in one range are assigned the same display style. The available range methods that are used to create ranges are equal interval, square root, standard deviation, logarithm and quantile. The thematic variable used to create the ranges map should be of numerical type.

The unique value map.In a unique value map, the features with the same thematic values will be grouped together, and a display style is set for every group, such as color and symbol, which means the features with the same thematic values are displayed in the same style so that you can tell different classes apart.

The custom map.In a custom map, the user is free to design the thematic map. You can set a specific display style for every feature or record and save these settings in one or more fields, and create a thematic map based on these fields. In SuperMap, every symbol, line, or fill style have their IDs, and the color, symbol size, line width etc. can also be represented by numerical values, and this makes it convenient to display the features and data in a custom map.

The specified vector dataset. Because this constructor modifies the attribution information for the region dataset, dataset must not be "read-only".The field name of the color. The field for coloring must be of the integer type. It can be an existing attribute field in the region dataset, or some other custom field. If it is an existing field, it must be of the integer type. The system will modify the attribute values in this field, and assign 1, 2, 3, and 4 to the field values. If it is a custom field, the field name must be valid. In this case the system will first create this field in the region dataset and then assign 1, 2, 3, and 4 to the field values. Therefore the values in the coloring field include 1, 2, 3, and 4, representing 4 different colors. A four-color map can be generated based on this field.The color passed by the users for making the thematic map.There are no rules about the number of passed colors.
