Built for field correction.
Original benchmark coordinates can be approximate. BMGIS turns each visit into a chance to confirm, correct, or flag a mark for the next person in the field.

Check the mark
Use the written description and the map together to find the physical mark in the field.
3
Share evidence
Submit GPS photos, condition reports, and votes so the community coordinate becomes more useful over time.
Map first, evidence close.
The app keeps the working map, BM details, community photo, and confidence signals close together so the next visit starts with better context.
Original and community positions
Keep the source coordinate visible while moving trust toward verified field submissions.
Condition reports
Record damaged, destroyed, inaccessible, and not-found marks without turning one report into a final verdict.
Community confidence
Votes, repeat visits, and submitted photos help separate useful corrections from uncertain observations.
Clear about the data.
BMGIS is an independent field tool. It uses benchmark reference data from Malaysia's open data portal plus separate community observations, and it does not represent a government agency.
Reference data sources
Source pages: Semenanjung Malaysia (Datum DTGSM) and Sabah/Sarawak benchmark data. The listed publisher is Jabatan Ukur dan Pemetaan Malaysia (JUPEM).
Public contribution model
Signed-in users can submit GPS photos, votes, and condition reports. Community updates are kept separate from the original source records and are not official survey values.
