WMS:Project Explorer Contents for GIS Module – XMS Wiki

GIS layers are organized and displayed in the GIS module. This module can be used for displaying and converting GIS data, but data in this module is not meant to be used for watershed analysis directly. There are two general types of GIS layers that can be displayed, and there are various ways of reading GIS data. The two general types of GIS data include raster and vector GIS data. WMS can read either raster or vector GIS data into the GIS module and these data can be converted to various formats for use both inside and outside of WMS. To understand how data is stored and projected under the GIS module, it is important to understand how WMS reads the various types of raster and vector GIS data. First, WMS reads and displays point, line, and polygon shapefiles as GIS vector data. These data can be converted to feature objects and WMS has a rich set of options for preserving, modifying, and converting attributes and geometry from shapefiles to feature objects in the map module of WMS. Second, WMS has tools for reading, displaying, and converting several formats of raster and vector GIS data to other formats. WMS uses the GlobalMapper library of functions to read and convert nearly all the formats that can be read and displayed by GlobalMapper. This functionality is available for all WMS users who have a license that includes the GIS module. The GIS vector data read as a GlobalMapper object can be converted to a WMS point, line, or polygon shapefile type so the data can be converted to feature objects and used in the hydrologic modeling projects. When selecting the Get Online Maps button in WMS, WMS loads an online map that is either a standard image, a palette-based raster (such as a land use grid), or an elevation raster (such as a DEM). Finally, if there is a current license to ArcMap that includes ArcObjects and ArcObjects have been enabled, WMS can read any data that ArcGIS can read. If ArcObjects is not enabled, WMS can still read several raster and vector data formats through GlobalMapper. However, some formats only supported by ArcObjects cannot be read. Each type of data has a similar but different right-click menu that allows accessing some of the functions that are available. Some functionality is also available in the GIS module menus. Some menus are only available if ArcObjects has been enabled. A summary table listing the various types of data that can be read and displayed and some of the functionality available for the various types of data is shown below: Right-clicking on the main GIS Layers folder allows adding the various types of GIS data (open new GIS layers) or clear all data. If ArcObjects is enabled WMS cannot read the GlobalMapper GIS data types. Right-click on the GIS Data folder and clear all the GIS data to disable ArcObjects and read GlobalMapper GIS data using the Add GIS Data button or menu. With ArcObjects enabled, access exists to any type of data that can be read by ArcMap® and to some of the functionality of ArcMap® from inside of WMS. Right-clicking on a GIS layer has commands to Delete, Rename, Zoom to layer, view/set Properties, Open Attribute Table, or Set Layer Transparency. If the layer is a vector data layer then there is an option to Join Table to Layer. If the layer is a grid, an options exist to Write DEM ASCII File or Convert to DEM. A GIS Data layer can be deleted by right-clicking on the layer folder in the Project Explorer and selecting the Delete command. Source.
