GIS ObjectLand is a universal Geographic Information System for Windows. Key features: - creation of vector-raster maps with arbitrary structure of layers and feature types; - creation of themes. Theme is a user presentation of a map; - control of displaying features depending on the chosen scale; - spatial data input and editing by assigning feature coordinates and also by interactive drawing with mouse or digitizer; - sewing of separate pages of an imported map into one unified continuous map; - copying, merging, and moving maps, layers, and feature types between different geoinformation databases; - creation of tables of arbitrary structure; - creation of queries. Query is a user presentation of table built by setting search and sorting conditions, joining tables, calculations and using reference tables; - copying, merging, and moving tables and queries between different geoinformation databases; - setting arbitrary links between spatial and table information; - getting information about the feature selected on the map; - searching for features on the map by linked records; - creation of filters. Filter is conditions of feature visualization depending on spatial properties of features and linked table data; - creation of layouts. Layout is an output form combining spatial, table information and presentation elements; - import and export of table and spatial information for widespread data formats; - support of style libraries containing fonts, map symbols, line styles, hatches and fill styles; - style editors for displaying styles; - setting for users the access permissions to components; - multiuser data editing; - using and editing tables of external database (via ODBC) as linked tables; - providing automation COM interfaces for user applications.
