1 G EOGRAPHIC TOOLS AND RESOURCES MEASURE Evaluation

2 Lesson Objectives  Showcase geographic tools  Provide resources for geographic data

3 Review of Lesson 1 and 2  Everything happens somewhere  Geographic context can be used to link data  There are different ways that geographic data can be presented  It is important that a standard data schema be used to store geographic data in a database

4 Tools for Geographic Data and Analysis  Software  ArcGIS  QGIS  E2G  Resources  Data  Training

5 GIS G eographic I nformation S ystem

6 GIS  Manages spatial data  Supports geographic display (maps)  Facilitates spatial analysis

7 GIS  Important to find the software best suited to:  Analysis needs  Skillset of users  Cost
