Questions and answers

#I forgot my password

Cartema sends no reset emails. Ask your workspace's administrator, or MDVIA support, to set a new one; then change it yourself in Account → Change password.

#I cannot see an app, or a layer

Apps are shown to the members of their workspace (a public app to anyone with its link). If a colleague sees an app you do not, you may be in a different workspace — check Workspace at the top left — or your organisation has not added you. A layer that is on but not drawn may be outside the area you are looking at: use Zoom to layer in its options.

#The map is slow

Large layers — survey plans with tens of thousands of lines, high-resolution imagery — take a few seconds to draw the first time. Switch off what you do not need. Layers being edited are always fetched fresh, so they are slower to draw than delivered ones.

#A click does not select what I want to edit

In Edit features, only the layer chosen at the top of the panel can be picked, and a feature can only be picked once it is drawn on the map. If several layers lie on top of each other, choose the right one in the panel.

#Why is the height marked ≈?

Where the app has no terrain model of its own, the height under the pointer comes from a world terrain model with cells of about 30 m. It is good for “about how high”, a few metres out; it is not a survey.

#How exact are measurements and printed scales?

Distances and areas are computed on the Earth's surface (geodesic), from the data as it is in Cartema: as exact as the data. A printed sheet is made at the true scale shown on it. Check anything that matters against authoritative sources.

#Can I get my data out?

Selected features export as CSV with Selection → CSV. For whole layers or a full copy of your workspace's data in open formats, ask MDVIA.

#Where is my data kept?

On Cartema's own server in Germany, backed up every night. See the privacy policy.

#Who do I contact?

Your workspace's administrator for access and roles; for anything else, your contact at MDVIA.
