ES341 Database Management and Attribute Data in GIS
Software package that builds and manipulates databases Tools: data input search query retrieval manipulation output E g Microsoft Access ORACLE Geodatabase – a software system that stores both the spatial (map elements) and attribute data tables in a single database ArcGIS employs the geodatabase model |
What is the difference between spatial data and attribute data?
The spatial data is the where and attribute data can contain information about the what, where, and why. Attribute data provides characteristics about spatial data. Attribute data can be store as one of five different field types in a table or database: character, integer, floating, date, and BLOB.
What are the two components of GIS data?
There are two components to GIS data: spatial information (coordinate and projection information for spatial features) and attribute data. Attribute data is information appended in tabular format to spatial features. The spatial data is the where and attribute data can contain information about the what, where, and why.
What is a GIS & how does it work?
The GIS is an organized collection of Data ,Software, Hardware, Network , People, Procedures and Methods of Applications. 3. 3 GIS represents geographic data and map information as data layers. GIS is helpful to perform a lot of statistical and numerical analysis, on the data.
What is the data input process in GIS?
8. 8 4. The data input process in GIS: Any textual or tabular data than can be referenced to a geographic feature, e.g. a point, line, or area, can be input into a GIS. Attribute data is usually input by manual keying or via DBMS software. ASCII format is the default standard for the transfer and conversion of attribute information.
