What did this land look like ten years ago? Reading change from historical imagery
The current state of a parcel is only half the story. Historical imagery often answers when a wall appeared, when trees were planted, or whether a stream bed moved.
Field takeaways
- Historical imagery is the same area recorded on different dates.
- It gives fast preliminary context for boundary disputes, unpermitted construction and land-use change.
- Coverage has gaps; clouds, season and resolution limit interpretation.
- Imagery alone is not legal evidence; official determination is a separate process.
- In MapLab Survey you can use a historical basemap together with your measurements and notes.
What historical imagery is good for
When was this wall built, how old are these trees, did the road run here, has the stream bed moved? A single current image cannot answer those questions. Looking at the same area on earlier dates narrows down when a change happened. The common uses are boundary disagreements, unpermitted construction and land-use change over time.
Where the images come from
Open long-running satellite archives such as Landsat reach back decades but have coarse resolution. Dated archives of high-resolution commercial imagery show individual trees and building corners, yet they cover a shorter period and not every date exists for every location. Decide first whether you need to know when something changed or exactly where it is.
Using it in the field
Mark the parcel and the point of interest, switch the basemap to an earlier date, then capture both views and write down the dates. In MapLab Survey a historical basemap can sit under your current drawing, so today's measured boundary can be compared with the older trace directly.
Reading it carefully
Small positional shifts are normal because of terrain, viewing angle and building height. Do not read a few metres of difference as a moved boundary. Season also changes appearance, so compare similar times of year. Imagery is a strong indicator, but official cadastral and title records govern boundary and ownership questions.

MapLab Survey handles RTK/GNSS point capture, drawing, area and volume calculations and coordinate conversion, then exports to DXF, KML/KMZ, GeoJSON, Shapefile, GeoPackage, NCZ or CSV. Capture, calculation and export work offline. Live NTRIP corrections and online basemaps need a connection.
Frequently asked questions
How do I see older imagery of a parcel?
Find the area on the map, switch the basemap to a dated imagery archive and compare dates.
How far back can I go?
Open archives reach back decades; high-resolution dated imagery covers a shorter period and has gaps.
Is satellite imagery legal evidence?
Not on its own. Cadastral and title records govern boundary and ownership.
Does MapLab Survey show historical imagery?
Yes, as a dated basemap under your own drawings and measurements.
