ArcPad Allows ForArcPad Allows For
• Image display
• Creating and editing spatial data
• Navigation
• Ability to identify, query,
locate and display features
• Measuring
• Custom application development
Why Use ArcPad?Why Use ArcPad?
• Field data collection – time-consuming – error-prone
• Geographic data in the field – Paper maps– Sketches and notes hand recorded– Data manually entered into the GIS– Results inaccurate and delayed
• ArcPad allows information to be collected digitally– Provides field access to GIS data– Adds real-time capabilities – Allows for analysis, display, and
faster decision making in the field
Who Uses ArcPad?Who Uses ArcPad?
• Asset inventory
• Asset maintenance
• Inspections
• Incident reporting
• GIS analysis and
decision making

GPS andGIS
GPS andGIS
Integrating GPS into the GIS processIntegrating GPS into the GIS processIntegrating GPS into the GIS processIntegrating GPS into the GIS process
• GPS can be one of the various ways to collect data for GIS
• No need for digitizing maps or manually entering data
• Data is collected quickly and accurately
• Process for updating data is more efficient
Data collected for GIS can be stored as:Data collected for GIS can be stored as:
• Points
• Lines
• Area
Data Collection ConsiderationsData Collection Considerations
• Planning day around satellite positions
• Field conditions
• Accessibility
• Standard process for adding data attributes (data dictionaries)
Data DictionaryData Dictionary
• Equivalent to a paper form that you fill out with information about the feature
Data DictionaryData Dictionary
• Designed specific for what data is being collected about that feature
Data DictionaryData Dictionary
• Can be created to match existing shape file databases to ensure efficient update processes
Additional features that make GPS a beneficial part of the GIS processAdditional features that make GPS a beneficial part of the GIS process• Shape files or raster files can be used as
backgrounds
Additional features that make GPS a beneficial part of the GIS processAdditional features that make GPS a beneficial part of the GIS process• Existing data can be transferred into
waypoints for navigating purposes
Processing the Collected GPS DataProcessing the Collected GPS Data
• Transfer to a PC
• Differentially correct
• Change coordinate system
• Display/Manipulate data
• Export to GIS format
Managing the GPS dataManaging the GPS data
• Maintain efficient standards for entering, updating and collecting data
• Save time and space by minimizing redundancy of attributes
• Make sure the correct units, datum, and coordinate system is being used
