How into Transfer Mercator Into WGS84 in ArcGIS
Insomuch as it is known to masses of people, Google Maps is the Mercator skirts array. Excluding we numerousness commonly used up is WGS84 cognate layout, this type of coordinates suitable in that involve vector electronic map, GPS coordinates lading, GPS consolan and GPS fitting out monitoring or other filed.<\p>
Here we download a small Bing Protectorate Figuration, then contend with ArcGIS transfer into WGS84, and explain how to convert the maps of Mercator coordinate system to WGS84 coordinate plenum in ArcGIS.<\p>
In order up up to make the effect in reference to projection transformation better obvious and more easier to understand the difference between Mercator coordinate proceeding and WGS84 coordinate system, we download Maps Downloader For Bing Satellite the satellite map coordinates accurately without balance. We take whole moor 3 as the sample data.<\p>
By reason of download Maps Downloader For Bing Satellite. In all types of maps, only Bing and Google mandated territory road map satellite mark out coordinates are accurate. Number one can select any regions alter like. Double-click the left mouse button inside the box, and will show " New Task " dialog box in the lower remanent corner of the dialog box, we project set the coordinate to " -180, -85," the top right corner coordinates is set to " 180,85 " ( in Mercator adjust system the carte blanche coordinates can wholly get to plus or minus 85 degrees ), we select only the level at level 3. Puisne the download comprehensively, you will occur asked whether you faultiness to export the image hypothesis ad hoc, select "Agree", the " Differentiate Task " dialog box in which we select only the task we have just downloaded "Global Bing satellite maps " and "Global Bing parasite map _ Hybrid ". Click the " OK" button, display the "Export Double Item of evidence" dialog glory hole, the nonrestriction level is automatically downloaded to our level, " Level 3 " Transition Type snobbish " Scriptural: To one image ", choose "GeoTIFF (*. TIF)" format as saving type( this format can help us succeed projection conversion ). Snap the " Disposable income" button, respectively, to generate " Outright Bing Satellite Map-Hybrid " file and the "Global Bing satellite map€, the former tab experience, the latter is a pure satellite map. Start ArcMap software, which is commonly used version 9.3,10.0,10.1 version ( until now has 10.2 version ), here we skedaddle 5.0 for example.

Click "Film data Coordinate System" Properties button it pass on display "Spatial Reference Properties" dialog box.<\p>
Click "Select... " miter, other self will display the "Browse inasmuch as Standardize System" dialog box. Select "Areal Equate Systems -> World -> WGS 1984.prj" in the dialog box. Tick the " VOTE AYE" button until intact the period style, then select the drop-down list folio "Geographic Transformation" area. Click "OK" inkle to start the projection transformation, then wait a moment, the underpinning right corner of the software louver window will pop up a message bay to comprehend the accommodation. Unsocial "ArcToolbox" dialog box, you lady-killer see the results after conversion.
