Historical maps give Sengkang students a way to investigate how places were represented at different times. Start with one location and compare carefully, rather than treating an old map as a complete picture of everything that existed.
The National Archives of Singapore makes its map collection searchable through Archives Online. Its collection introduction describes survey, topographic and other maps from different periods.
This is a guide to finding and reading evidence. It does not assume that a particular map of Sengkang is available, fully digitised or detailed enough for your project.

Define the place and question
Choose a small question: how a waterway was labelled, which roads were drawn, or how a selected area appeared on two dated maps.
Write down the modern place name and nearby features that may help locate it. Earlier maps may use different labels or cover the area without using today’s town name.
Search the NAS maps and building-plans collection, then read each record’s title and description before deciding whether it fits.
Check the date, purpose and scale
Record the map’s creator, date, reference number and coverage. Notice whether the record describes an original map, a later edition or a reproduction.
Find the scale and legend where they are provided. A small-scale map of the whole island cannot be expected to show the same detail as a neighbourhood plan.
Ask what the map was made to show. A transport map, survey map and land-use plan may emphasise different features; a blank-looking patch is not proof that nothing was there.
Compare like with like
Choose two maps that cover a sufficiently similar area. Locate a shared feature before comparing their roads, labels or boundaries.
Keep two columns in your notes: what is visible and what you think it means. A feature appearing on one map but not another might reflect change, different scale or a different mapping purpose.
Write a narrow conclusion that the maps support. Avoid giving an exact construction or removal date solely because a feature appears differently between two map editions.
Add another source before finishing
Use a dated photograph, report or other suitable record to test your interpretation. Our NewspaperSG guide offers one route for finding contemporary reports.
Check the record’s access and use conditions before reproducing a map in an assignment or public presentation. Finding an image online does not settle every reuse question.
Finish with the two map references, one clear comparison and any remaining uncertainty. That is a stronger research result than a confident story built from an unread legend.
