GIS ObjectLand

GIS ObjectLand processes data organized as geoinformation database (GDB). Basic GDB components are maps, themes, tables, queries, external databases, layouts, users, and styles.

Familiarize with the documentation and see screenshots.

System Requirements

GIS ObjectLand runs on a standard PC under Windows 95, 98, ME, NT4, NT2000, XP, 2003. Installation package includes full documentation and online help.

Capabilities

• creation of vector-raster maps with arbitrary structure of layers and feature types;

• advanced tools for spatial data analysis;

• 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;

Geoinformation Database

Geoinformation database (GDB) is the main data storage for GIS ObjectLand. Geoinformation database is located on a disk and contains the following components:

• maps – structured set of spatial features;

• themes – thematic (user defined) map presentations;

• tables – sets of records in relational database;

• queries – thematic (user defined) table presentations;

• external databases – components for access to tables from external databases (via ODBC);

• layouts – presentations of output documents combining different forms of spatial and table data;

• users – list of persons with access permissions to GDB components;

• style library (fonts, map symbols, line styles, hatches, and fill styles).

There are no practical limitations on the number of each GDB component. GDB is always consists of nine or ten files regardless of the number of components.
