Geographic Information Data Download (DEM) Assistant

Geographic information data download (DEM) assistant is a software that provides map, satellite map download, contour drawing and other functions.Elevation data download dem assistant, you can set any density and range. The data extracted by this software can be easily generated by third-party software to generate contours, three-dimensional terrain, elevation profiles, etc. It is a powerful assistant in geology, transportation, agriculture, forestry, and planning.

Function introduction

(1) Map mode: Earth, Moon and Mars modes, which can be switched at will.

(2) Draw graphics: Freely draw point (landmark), line (path), surface (triangle, rectangle, polygon, circle and sector) shape graphics.

(3) Measurement tools: measure the distance between two points, path length, area and peripheral perimeter of surface objects (triangle, rectangle, polygon, circle and sector).

(4) Format conversion: EXCEL data to KML files, KML files to EXCEL data, batch import and conversion of graphics (points, lines and surfaces) can be realized, and it is compatible with CSV and txt file formats.

(5) Coordinate extraction: Geographical coordinates can be extracted in batches based on landmarks, paths and polygons for the earth's land, oceans, moon and Mars, including name, longitude, latitude and elevation information. The spacing between sampling points can be set arbitrarily, and the optimum can be customized Sampling plan, fully automatic collection of millions (no upper limit) elevation point data at a time, without time or quantity restrictions.

(6) Layer settings: Map layers can be displayed and turned off, and the display status can be easily switched at will.

(7) Location search: The location can be automatically searched based on the input longitude and latitude, or the longitude and latitude can be searched based on the address (place name) to achieve precise positioning.

(8) Coordinate unit conversion: "Decimal degree" unit coordinates and "degrees, minutes and seconds" unit coordinates can be converted to each other.

(9) Import and export: KML files can be imported and KML files can also be exported, making the software data format compatible with other software formats.
