GeoSTAC Tools: Hardware and Software Requirements
The GeoSTAC Toolset is additional software that runs inside ArcGIS. The ArcGIS package requires significant system resources for acceptable performance as described below. In addition, the GeoSTAC datasets will consume considerable disk space. This page lists minimal system and storage requirements and also contains some suggestions on specifications (for new machines or upgrading) that can offer improved system performance when running GeoSTAC.
About the Tools
- Simple Join Tool
- Feature and Attribute Extraction Tool
- Data Summary and Aggregation Tool
- Linear Feature Summary Tool
- Doane Aggregation / Disaggregation Tool
- Proximity Analysis Tool
System and GIS Software
- Windows XP Professional SP3 (See ESRI website for limitations)
- ESRI ArcGIS 9.3/9.3.1 (ArcView-level license)
- ESRI ArcGIS Spatial Analyst Extension
CLA recommends that potential purchasers of ESRI software review the latest minimum requirements currently specified by ESRI at this website. These should be sufficient for the basic functions of ArcGIS 9.3 with Spatial Analyst.
To run GeoSTAC, a minimum of approximately 1GB of hard disk space will be needed to download and install the tools, along with about 7.5GB of hard disk space to hold a minimum set of the geographical data. The full set of GeoSTAC datasets will occupy approximately 123GB of either internal or external disk space.
For complex analyses, the GeoSTAC Tools can query millions of database records. On a minimally-configured system, performance is likely to be degraded for such operations, although our testing has indicated that the system will run. System upgrades in processor speed, RAM, hard disk access times and hard disk spin speeds can offer significant improvements in performance and are highly recommended.
