Introduction. We have been producing a web-based, user-friendly interface built on a powerful Geographic Information System (GIS) that integrates statistical and spatial relational tools for analyses of planetary datasets. The interface, known as "Planetary Interactive GIS-on-the-Web Analyzable Database" (PIGWAD), provides database support for the research and academic planetary science communities, particularly for geologic mapping and other surface-related investigations. The PIGWAD address is http://webgis.wr.usgs.gov. We are now implementing a Mars '01 Lander page to support that mission's landing-site selection activity. GIS is an organized collection of computer hardware, software, and geographic data whose operations can be tailored to efficiently capture, store, update, manipulate, analyze, and display all forms of geographically referenced information. Application of GIS in the planetary sciences has grown dramatically over the past few years, as scientists have been able to prepare thematic maps and determine spatial relations among multiple datasets.
