TerraTopo saves surveys to your company's account so anyone on the team can open them. You can also download the heatmap as a picture and compare a new visit to an earlier one.

Save and open projects

  1. Click Save to my account. If the project has no name yet, type the address when asked.
  2. Click My projects. Your company's jobs open full screen as address folders, one per house, the same as in every Terralox program. Search an address, a customer, a JobTread job number or a status.
  3. Tap a house's folder, then:
    • Start a survey opens the house's survey. If it doesn't have one yet, a survey starts on its TerraPlan drawing (scale and house outline set), or in its JobTread job.
    • On the Work tab, Open in TerraTopo opens a survey, Use as baseline compares the open survey against it, and Delete deletes it.
  4. New job asks for the address first. Load the plan in Step 1, add readings and Save: the survey is filed in that house's folder.
  5. ‹ Back to the survey closes My projects.

Download the heatmap picture

  1. Under 11. Export & save survey, fill in Project / address and Notes. They print in the corner of the picture with the date.
  2. Tick Include scale bar (requires Step 5) and Include orientation arrow if you want them.
  3. Click Download heatmap PNG. The picture downloads to your device, ready to email or put in a report.
Step 11 with the Download heatmap PNG and Save survey data (JSON) buttons
Step 11 with the Download heatmap PNG and Save survey data (JSON) buttons

Save survey data (JSON) downloads the survey as a file, with every point, note, outline, the foundation profile and the scale. Load the same plan, then use Re-open a saved survey (JSON) to continue from it.

Compare to an earlier visit

  1. Open the earlier survey and click Save as copy (keep the original). Name it for the new visit, for example "123 Demo St – visit Oct 21". The original stays as it was.
  2. Update the readings for the new visit and save.
  3. Click My projects, open the house's folder, and on the Work tab click Use as baseline on the earlier visit. (The copy is filed in the same house's folder.)
  4. Show movement since baseline turns on. Set Flag movement greater than (in) to mark the spots that moved more than that.

You can also load a baseline from a file under 12. Compare to a previous survey.

Does saving keep the plan picture?

Yes, when the plan file is 4 MB or less. Bigger plans save the survey only. See TerraTopo won't open my saved plan.
