GIS DATA WORKFLOW
Update GIS data from spreadsheets with less manual work.
See how CSV or Excel records can be matched to existing GIS features using Connect-ID, then applied through a workflow you can run again when new data arrives.
The problem
Updating GIS data shouldn't mean rebuilding it manually.
Teams often receive attribute or status updates in spreadsheets while the authoritative geometry lives in GIS — matching the two is repetitive and error-prone.
- Identifying the correct existing features
- Matching spreadsheet records to GIS data
- Reducing repetitive manual update work
- Maintaining a repeatable update process
Why SEPM
A clearer path from source data to usable results.
Connect-ID helps align incoming records with GIS features so updates can follow a defined process instead of ad hoc edits.
- 01
Connect-ID matching
Use Connect-ID to relate spreadsheet rows to the corresponding GIS features according to the supported identification workflow.
- 02
CSV & Excel in the loop
Work from familiar tabular sources; preparation and column mapping still matter before updates are applied.
- 03
Repeatable updates
Once configured, the same workflow can support recurring data drops — subject to your data model and validation rules.
- 04
Review before you commit
Inspect matches and outcomes so corrections happen before updated data reaches production systems.

Follow the process, from the initial data to the final result.
Workflow steps
- 01
Prepare the spreadsheet
Start with a CSV or Excel file containing the records you need to apply to the GIS.
- 02
Identify corresponding features
Use Connect-ID to match incoming rows with the appropriate GIS features.
- 03
Apply the update workflow
Run the configured transfer so matched records update the relevant attributes or linked data.
- 04
Review the result
Validate updated features and resolve exceptions before wider publication.
Products & technologies
Expected outcome
Targeted updates instead of manual rebuilds
Spreadsheet-driven changes reach the right GIS features through a documented workflow — reducing repetitive editing while keeping you in control of validation.
