Set your GIS project coordinate system before adding data.
Use projected coordinate systems (UTM, State Plane) for area/length calculations.
Keep metadata for every dataset you collect in the field.
Record GPS accuracy with every waypoint.
Use differential GPS (DGPS/RTK) when precision below 1 m is required.
Carry extra power banks or solar chargers in the field.
Sync your GPS device clock with your computer before collecting data.
Collect redundant waypoints to identify outliers later.
In ArcGIS Pro, enable snapping to digitize accurately.
Use domains and subtypes in geodatabases to enforce attribute consistency.
Backup field notes on waterproof paper in addition to digital devices.
Export field GPS data as GPX or shapefiles for easy GIS import.
Use mobile GIS apps like Collector, Field Maps, or QField for real-time mapping.
Calibrate your compass before every field trip.
Always note datum (WGS84, NAD83, etc.) when recording coordinates.
Reproject rasters before performing spatial analysis to avoid misalignment.
For field sampling, randomize sample points with ArcGIS Create Random Points tool.
Use georeferenced aerial imagery to guide navigation in the field.
Learn keyboard shortcuts (e.g., ArcGIS Pro “C” for pan).
Store raw GPS logs in addition to processed shapefiles.
Use feature templates to speed up consistent digitizing.
Field sketch maps should be scanned and georeferenced for archival.
Check elevation values for GPS points against DEMs to detect errors.
Practice geotagging photos for later integration with GIS.
Use ArcGIS Pro’s Add XY Data for quick conversion of coordinate spreadsheets.
Carry laminated topo maps as backup in case of device failure.
ArcGIS Near tool is useful for calculating distances to features.
Learn how to create hillshades for better visualization of topography.
Always test GIS scripts/tools on a small dataset before batch running.
In ArcGIS, use definition queries to simplify large datasets.
Use GPS averaging (30–60 seconds) for better accuracy at each point.
Convert GPS data into projected coordinates immediately after download.
Document coordinate precision (e.g., 6 decimal places for lat/long ? 0.1 m).
Raster cell size should not exceed half the minimum mapping unit you need.
Save frequently in the field when using mobile GIS apps—crashes happen.
ArcGIS Clip is safer than Erase when preserving original data.
Carry a compass-clinometer for structural geology measurements.
Log soil, rock, or sample ID codes directly in GIS attribute tables.
Learn SQL queries in ArcGIS for advanced attribute selection.
Collect duplicate samples to verify lab analyses.
Digitize features at the scale of their intended use, not larger.
Store GIS data in file geodatabases, not shapefiles, when possible.
Use polygon outlines for sampling grids rather than relying only on points.
Build geoprocessing models in ModelBuilder for repeatable workflows.
Never store final data only on field laptops—use cloud or external drives.
Use a handheld altimeter to validate GPS elevations.
Keep projection units consistent across datasets before overlay analysis.
ArcGIS Spatial Join is powerful for merging field attributes with base data.
Waterproof labels are essential for physical samples.
Use Calculate Geometry to populate area, length, or centroid fields.
