*GIS Resource Guide* prepared by JL Wilson, UC Davis, J Kwan, California Department of Public Health, and D Fisher and R Laffey, Sacramento-Yolo Mosquito and Vector Control District, as part of a GIS Workshop at the 2009 Annual Conference of the Mosquito and Vector Control Association of California.
*Downloadable GIS Software*
* Google Earth: http://earth.google.com/ Google Earth offers maps and satellite images for complex or pinpointed regional searches
* ArcExplorer: http://www.esri.com/software/arcgis/explorer/index.html
ArcExplorer is a lightweight GIS data viewer written in Java that is used to perform basic GIS functions (e.g., view, navigate, and query). It is a downloadable application that operates in a stand-alone environment and does not need to connect to a server
* Minnesota Department of Natural Resources Garmin GPS Application: Site
This extension was built to provide users the ability to directly transfer data between Garmin GPS handheld receivers and various GIS software packages. Using this program a user can use point features (graphics or shapefile) and upload them to the GPS as waypoints. Line and polygon graphics or shapes can be uploaded to the GPS as Track Logs or Routes. Conversely, Waypoints, Track Logs, and Routes collected using the GPS can be transferred directly to ArcView/ArcMap/Google Earth/Landview and saved as graphics or shapefiles.
* MapInfo: http://www.mapinfo.com/ Pitney Bowes MapInfo has created a comprehensive list of tools to help you manage, visualize and capitalize on location intelligence
* Maptech Terrain Navigator: Site Maptech provides regional collections of USGS topo maps and Software for 2-D and 3-D viewing, customizing, printing, and GPS.
*Free Sources for Online Mapping Information *
* Geography Network: http://www.geographynetwork.com/ The Geography Network is a global network of geographic information users and providers. It provides the infrastructure needed to support the sharing of geographic information among data providers, service providers, and users around the world. Through the Geography Network, you can access many types of geographic content including dynamic maps, downloadable data, and more advanced Web services.
* Environmental Systems Research Institute (ESRI) Resources: Site ESRI provides free maps at this site to use in your ArcGIS applications.
* ESRI tech article regarding projections: Site This site describes how to identify the spatial reference, projection, or coordinate system of data.
* ESRI tech article; Projection Basics Site This site provides concepts that are fundamental to understanding the use of map projections in ArcGIS.
* GISDATA Map Studio: http://gisdata.usgs.gov/ This is a site hosted at the USGS Earth Resources Observation and Science (EROS) by the USGS. Here you will find public web map services, and interfaces developed at the center. Many of the public web map services are published on the Geography Network, and some national services are cohosted by ESRI.
* The National Map Seamless Server: http://seamless.usgs.gov/ This site, hosted by the U.S. Geological Survey (USGS) and the EROS Data Center (EDC) offers free downloads of national base layers, as well as other geospatial data layers. These layers are divided into framework categories: Places, Structures, Transportation, Boundaries, Hydrography, Orthoimagery, Land Cover and Elevation.
* US Census Bureau: http://www.census.gov/ The Census Bureau serves as the leading source of quality data about the nation's people and economy.
* USGS Maps, Imagery, and Publications: http://www.usgs.gov/pubprod/ USGS maps range from detailed local areas to the world. Because they can show many kinds of information, they are excellent for a wide range of uses, including emergency response, outdoor recreation, scientific research, and resource management.
* Lat Lon conversion: http://www.cellspark.com/UTM.html This site will convert your latitude and longitude coordinates into decimal degrees, degrees, minutes, seconds, or northing, easting values.
* A Geospatial Librarian's World: http://gothos.info/ General GIS info, including reasons for using open source GIS.
* Convert Excel to KML (Google Earth): http://www.earthpoint.us/ExcelToKml.aspx This site exports a spreadsheet of latitude and longitude coordinates to Google Earth.
*Free Tools for Spatial Analyses*
* Cluster Analysis Software: Site SaTScan&tm; is a free software that analyzes spatial, temporal and space-time data using the spatial, temporal, or space-time scan
* Risk Analysis Software: Site (30 day free trial, more of an application for risk analysis, decision making) TreePlan helps you build a decision tree diagram in an Excel worksheet using dialog boxes. Decision trees are useful for analyzing sequential decision problems under uncertainty.
* Spatial analysis: Site http://www.spatialanalysisonline.com/ This guide addresses the full spectrum of analytical techniques that are provided within modern GIS and related geospatial software products. It is broad in its treatment of concepts and methods and representative in terms of the software that people actually use.
* Nearest Neighbor Analysis: Site Calculates a nearest neighbor index based on the average distance from each feature to its nearest neighboring feature.
* Simple Kriging: Site Simple Kriging assumes that the data have a known, constant, mean value throughout the study area and exhibits second order stationarity.
