![]() You can now export the shape to your GIS software in shapefile format, or click View in Google Earth to see the lake or property boundary over the aerial imagery in Google Earth. If you calculate area, ExpertGPS will subtract out the area of any inner polygons, giving you the correct acreage of your lake or property. ![]() ExpertGPS will recognize the inner holes and leave them unfilled. Right click, and click Join Shapes to convert the selected shapes into one composite shape. Once the two shapes are drawn, select both by clicking the outer one with the Select tool, holding Shift, and selecting the inner one (or ones, if there are multiple holes). Add the shape points in counter-clockwise order! This is important – most GIS and 3D systems consider counter-clockwise polygons to be inner holes. I then drew the inner hole using the shape tool. (This happens automatically when you select a filled shape type) chromebook bios Convert any coordinate format or datum with ExpertGPS. I clicked to draw the four corners, and then pressed Enter to finish the drawing and connect the fourth corner back to the start. 3- Using the edit tool, Change the size of your rectangle to make it long and. borderWidth3 and borderColorblack and part within rectangle dont have content or color.

Drawing Assembly: Draws a rectangle specified by a coordinate pair, a width, and a height. Here’s how to create the “donut” shown at right.īegin by drawing the outer shape, using the shape tool. You can also drag a zoom rectangle over the map to zoom in on a specific object. You can use this feature to draw lakes with islands,Ī park boundary with private land inholdings, or other complex shapes. the display), the color, the rectangle and the optional outline width.

Some examples: draws filled rectangular shapes or outlines. ![]() The strange part is when you zoom in, the lake polygon will fill then if you zoom out, it empties.ĮxpertGPS Pro allows you to draw, view, and import polygons with complex geometry, including filled objects with holes in them. With the module pygame.draw shapes like rectangles, circles, polygons, liens, ellipses or arcs can be drawn. When I export as a kml, the fill of the polygon is not complete. When I export as a gpx, it creates a polyline where the end node of the lake outline connects to the end nodes of each of the islands. What is the best method to create a gpx or kml file of an area filled polygon that has islands (a lake shp file).
