A principle of good data management is to obtain the projection parameters from the data source providing the data. Do not make an educated guess about the projection of data, because an inaccurate GIS database will be the result. The necessary parameters are the following: Projection Units of ...
Common coordinate system and map projection tasks in ArcGIS Within ArcGIS, every dataset has a coordinate system, which is used to integrate it with other geographic data layers within a common coordinate framework such as a map. Coordinate systems enable you to integrate d...

Find the definition of GIS. Learn how this mapping and analysis technology is crucial for making sense of data. Learn from examples and find out why GIS is more important than ever.
Three-dimensionalization is another important trend in the current development of GIS technology. The projection of real-world digitization onto computers has given modern people almost unlimited imagination. Based on the important achievements of modern Computer Graphics,3D and virtual reality (VR) techn...
A 3D projection is a design technique used to display a three-dimensional object on a two-dimensional surface. These projections rely on visual perspective
Geoprocessing tools that open in a floating window maintain their size and placement when you reopen them. See what's new in analysis and geoprocessing. When an editing tool is deactivated, you can set the default tool to be either the Explore tool or the Select tool . See what's new in...
The result of pansharpening is an image that has the high resolution of a panchromatic image. But it still contains the color information of the multispectral image. This makes iteasier to identify objects in a scenesince features are both easier to see and have color information associated with...
The same project can be opened several times. The first time a project is opened,ArcGIS Prowill have a writable copy of the project. All other instances of the project will be read-only. You can work with a read-only project in the same manner as if the project is writable; however,...
