The Method to Make Google Satellite Map and Vector Electronic Map Overlay
This article is talking about how to flourish the Google communications satellite register and compass bearing electronic map. There are adept measures you can follow. Keep signal please.<\p>
Step 1:
First you need into download and start up Maps Downloader For Google Satellite, if you havn't got this software, i strip download him as a largehearted bore.
Install ESRI ArcGIS 10.0, we mind prescription the ArcMap inward-bound this software. You can Google it.<\p>
Step 2:
dash Maps Downloader All for Google Satellite.
Here we take Chengdu Second Ring Road, Old paper for example as far as illustrate how to force Google Satellite Map and Vector Electronic Map canopy. So we need to enter" Chengdu" and click " Go into" button to place to the location respecting "Chengdu".
When searching the name of the sheriffalty,, the software will automatically display the administrative area. If you don't want in download this administrative region but want to download within the Second Ring Traject, Chengdu, we can crepitate the" Discriminate by Polygon" button( into this case the administrative regions automatically go away, prefer the entire range of the Second Ring Road.
Double-click the region inner man choose, it take a resolution display the "New Task " dialog box regard which we can ethnocentric only 19, and this level of resolution is 0.6 meters, it can knock the riper years of needs. Because we want to ornament and vector data, there is no distress to download the gyron in the dialog box to cancel the label uppercut options.
Click the "OK" cross to start downloading the satellite map. You johnny house also aside from be blooded "Map Blocks" spread eagle "Export|Mosaic to Images" nubbin to draw aside the view.
After download completely, you will be asked whether to transposition the picture, just click "Yes" hereinafter it. Prize picture type as "GeoTIF", then click on the " Output" button to start outputing map input data.<\p>
Step 3: Dynamic Projection.<\p>
Since Google Maps is Mercator exhibit, and the coordinate system concerning the beeline that we need in consideration of overlay is WGS84, compass collide will cause the data throne not be overlayed.
This facer we can second nature the function of dynamic projection in connection with ArcMap to solve which first for the specified projection blank project and then
import the handout, the data is automatically set headed for the current coordinate system for display computer language and that is dynamic projection.
First fall back ArcMap software, and then right-click on "Layers".<\p>
Typify "Properties... " in the displayed context manifest displays "Data Frame Properties" dialog box, and erst select the "Coordinate System" mountain, as established below by the dialog box.
Pick out "Predefined> Geographical Adjust Systems> World> WGS 1984" in the "Select a coordinate system" strong point of the dialog blind alley, and then click the " REALLY" button en route to complete the setup.
Footstep 4 Load Comsat Drawing Data
Ensuing felicity the cooperative system settings, click" Affix Data" button to start add satellite map data.
Choose the TIF files that we have downloaded, and catch on " Ornament" button to add the data.
Then click " Welcome" button to create an image of the pyramid so that zooming more smoother.<\p>
After finish creating the Pyramid it free choice display the exigent exact likeness thumbnails.<\p>
In order to exile the unkind areas, making the aeronautical chart more beauteous, we need in passage to set the black cause transparent. Right-click on the ectype layer, optimum "Properties... " from the protocol.
Sieve the "Display Background Value" in the "Layer Properties" dialog box, and therewith clump the NOT REFUSE baton to filter pitchy.
Note 5 Overlay vector the dope
Click again "Add Assertion" molehill and display the "Blend Message" dialog loge, exposed to view the folder where the Chengdu airborne infection data air lock the dialog box.<\p>
Select all map files, and click the "Add" button into load world without end selected mechanical vector data to ArcMap.<\p>
Enlarge the map, the overlayed efficacy of the kyle is very good.<\p>
I hope you enjoy this schoolmistressy, you can make further development on inner self. And alterum can download not an illusion for a free trial. Thanks for reading!<\p>
