.pro files

cgcbar2kml.pro

This program creates a KML file that can be opened in Google Earth to display a color bar as a ScreenOverlay.

cgchangemapprojection.pro

This function warps a map projected image from one map projection to another, using Map_Proj_Image to do the warping.

cgcliptomap.pro

Allows an image or geoTiff file to be clipped or subset to a map projected boundary.

cgcontainer__define.pro

A modified IDL container with properties needed for Coyote Graphics routines.

cgcoord__define.pro

An object for maintaining a coordinate system for data annotation or display.

cgdrawshapes.pro

This program draws the entities in a shapefile, containing latitude and longitude polygons or polylines, on a map projection.

cgfindmapboundary.pro

Utility routine to find the map projection grid boundary from a file, if it is possible to do so.

cggeomap.pro

The purpose of this function is to translate a GEOTIFF structure (as returned by QUERY_TIFF or READ_TIFF) into a map coordinate object (cgMap) that can be used to georeference images with a map data coordinate system.

cggeomosaic.pro

Creates a mosaic or combination image, given the names of two GeoTiff image files.

cggoogle_metersperpixel.pro

This funtion returns the number of meters per pixel for a particular zoom level in images returned using Google's Static Image API.

cggooglemapmarker__define.pro

This program is the definition module for a Google Map Marker structure, which is used in the GoogleMapWidget object to add markers to Google Static Map images.

cggooglemapwidget.pro

This is the driver for the cgGoogleMapWidget object, which is a compound widget object that obtains a Google static map from Google Maps and displays it in the program's draw widget window.

cggooglemapwidget__define.pro

This is a compound widget object that obtains a Google static map from Google Maps and displays it in the program's draw widget window.

cgimage2kml.pro

This program creates a KML file that can be opened in Google Earth to display the image drapped over the Google Earth terrain.

cgkml2kmz.pro

This program simply collects files created from the cgImage2KML program and moves the files to a zip file with a *.kmz file extention.

cgkml_feature__define.pro

This program implements the KML abstract FEATURE class.

cgkml_file__define.pro

This program creates a KML file that can be displayed with Google Earth.

cgkml_groundoverlay__define.pro

This program implements the KML GroundOverlay element.

cgkml_lookat__define.pro

This program implements the KML abstract LookAt class.

cgkml_object__define.pro

This program implements the KML abstract OBJECT class.

cgkml_overlay__define.pro

This program implements the KML abstract OVERLAY class.

cgkml_screenoverlay__define.pro

This program implements the KML ScreenOverlay element.

cgmap__define.pro

Provides an easy way to set up a map projection coordinate space using GCTP map projections normally accessed via Map_Proj_Init.

cgmap_continents.pro

Provides a simple wrapper to the MAP_CONTINENTS command in IDL that can be used to draw map continental outlines in a device and color independent way with Coyote Graphics programs.

cgmap_grid.pro

This program provides a significantly modified MAP_GRID command that can be used with other Coyote Graphics routines.

cgmap_gshhs.pro

The program uses files from the Globally Self-consistent Hierarchical High-resolution Shoreline (GSHHS) data base to draw shorelines in the manner of MAP_CONTINENTS.

cgmap_set.pro

Provides a modified MAP_SET command that can work together with other Coyote Graphics commands and be used in resizeable graphics windows.

cgmapcontinents__define.pro

Provides an object wrapper to the cgMAP_CONTINENTS or the cgMap_GSHHS commands.

cgmapgrid__define.pro

This object is a wrapper for the cgMap_Grid routine in IDL.

cgmapplots__define.pro

This object is a wrapper for the cgPlotS routine in IDL.

cgmapvector__define.pro

This is the class definition module.

cgncdfmap.pro

The purpose of this function is to translate map projection information found in a netCDF file into a map coordinate object (cgMap) that can be used to georeference images with a map data coordinate system.

cgshapeinfo.pro

The purpose of this program is allow the user to browse a very narrow selection of shapefiles.

cgshapepointfile.pro

The purpose of this program is to create a shapefile filled with multiple individual points as entities.

cgshaperange.pro

Determines the X (longitude) and Y (latitude) data range of the entities in a shapefile.

cgteminatormap.pro

This is a program for viewing a map of the Earth in several different projections with a day/night terminator.

cgterminatormap.pro

This is a program for viewing a map of the Earth in several different projections with a day/night terminator.

cgutmzone.pro

This function returns the correct UTM zone for UTM map projections, given a longitude and latitude value.

cgwarptomap.pro

The purpose of this function is to warp an image into a map projection, given latitude and longitude values for each data point.
