About MapMaker


This page is provided for users, web developers, and software developers.

MapMaker is PDS software that gives easy access to Digital Image Map (DIM) products. Many DIM products are laid out in a tiling scheme as follows:



Because of the large size of some of our data sets, they are broken up into a series of tiles that make up the whole area of the planet represented. These tiles are often archived on multiple CDs. This can present a problem, however, as points of interest often lie between tile or CD boundaries, making them difficult to view.

MapMaker solves this problem by making tailored maps according to the users specifications. A user gives MapMaker information about latitude and longitude limits, scale, etc, and Map Maker creates the map out of the tiles, making a single continuous image across the boundaries:



MapMaker Features:

Nearest neighbor resampling.

Scale given as deg/pixel or km/pixel so Map Maker can choose optimum tiles to use.
