Map Searches — Location Based

Our map search tool makes finding historical maps fast and intuitive. Simply right-click or long-tap any location to see a list of relevant map suggestions, all presented in chronological order. This allows to “travel through time” by exploring the results one by one.

Map Rotation

Historical maps sometimes have a different orientation, with North not always at the top. Our map rotation tools let you adjust the map to any angle. Use the compass button to toggle between the modern North-up view and the original orientation of the historical map — or to quickly reset the map to North-up from any rotation. For full control, press SHIFT while using the mouse wheel to rotate freely. This keeps labels readable and exploration intuitive, even on maps from the 1600s.

Location Searches

The location search makes it easy to find places by name and explore their history. Selecting a result focuses the map and adds an orange marker with related map suggestions and data links. Because each result is stored in the page address, searches can be bookmarked or shared — making discoveries easy to revisit and share with others.

Interactive Markers

Marker layers add curated points of interest to the map, such as administrative areas or heritage sites. When markers are close together, they cluster automatically, showing a counter with the number of grouped markers. Selecting a marker opens related historical maps and data links, making it easy to explore connected locations and themes.

Map Attachments

Map Attachments provide access to supporting materials that belong with a historical map — such as reference tables listing tenants and soil types, or full original scans that reveal the map image is a certified copy created centuries later. Attachments open as full overlays and can be explored just like maps, with zooming and panning for close inspection.

Bookmarks & Sharing

Each map view and search result is recorded in the web address. The map layer, zoom level, and location are all preserved, so you can bookmark your findings or share them by copying their address — a simple way to build and revisit your research trail.

Help Pages

We offer professionally designed, custom-tailored start and help pages for your map system. Following modern responsive design principles, they adapt smoothly to any screen or window size, just like the map system itself. Heavily illustrated with interactive screenshots, the pages make exploring the maps intuitive and engaging — novices and experts alike can quickly find what they’re looking for and jump straight to the relevant map view. Each page covers the main system features and provides background information about the maps on offer.

Map Image Processing

We transform scanned maps into online tile layers, ready for use in your system. Each image is carefully enhanced, georeferenced, and optimized for size to display at multiple zoom levels. The resulting layers integrate seamlessly with modern maps like OpenStreetMap.
