ISAMUD (Integrated System for Analysis and Management of Ungulate Data) is an integrated and modular software platform developed to manage GPS collar data for wildlife management. It is based on an open source spatial database (PostgreSQL and PostGIS) and includes open source data management, geo-statistical analysis and Web services modules (R, QGIS, GRASS, MapServer, Ka-Map) and a proprietary database front-end (MS Access). It is able to store, retrieve, update, analyze, visualize and disseminate GPS telemetry data in an efficient and consistent way, with a high degree of automatization.
