Overview

mapa 🌍

Create 3d-printable STLs from satellite elevation data

Installation

pip install mapa

Usage

mapa uses numpy and numba under the hood to crunch large amounts of data in little time.

1. Using the dem2stl cli

The dem2stl cli lets you create a 3d-printable STL file based on your tiff file. You can run a demo computation to get a feeling of how the output STL will look like:

dem2stl demo

If you have your tiff file ready, you may run something like

dem2stl --input your_file.tiff --output output.stl --model-size 200 --z-offset 3.0 --z-scale 1.5

For more details on the different options, check out the docs.

2. Using the mapa interactive map

If you don't have a tiff file handy, you may simple select your favorite region using the mapa cli. Simply type

mapa

A jupyter notebook will be started with an interactive map. Follow the described steps by executing the cells to create a 3d model of whatever place you like.

3. Using mapa as python library

In case you are building your own application you can simply use mapa's functionality as a within your application by importing the modules functions.

from mapa import convert_tif_to_stl

path_to_stl = convert_tif_to_stl(...)

Refer to the docs for more details.

Bug: bottom surface not connected
The generated model's bottom surface has two flaws:

It is not connected to the side walls so those edges down there are all open. This was reported in the slicer and I verified it in an 3D-tool.

It is not triangulated properly (only once into two triangles): all those edges coming down the side walls from the top relief end and are not continued further to e.g. a center vertex. This results in two massive n-gons the bottom surface is made of.

Maybe these two issues are related?

feature request: tiled area

How about offering the possibility to cut the selected (square) area into (square) tiles - 3x3 & 4x4 should be sufficient. With this feature it would be possible to print a larger area in pieces that can be glued together.

Units

This is probably not very important, but it would be nice to have units displayed. For example there's no unit shown on the Z-offset slider. Since this value is directly related to the resulting object's dimensions it would be nice, too to show some information about how large the resulting model will be.

Typical use case: I want the object to be exactly 1cm thick (base height). I set that and generate the object. In my slicer I notice, the object is too large for my printer and I have to scale it down by 50%. Now my object is only 0.5cm thick. Arrrgh! Back to the website, set the offset to 2cm, re-generate, ...

Dream-solution A: after the rectangle has been drawn, the dimensions are displayed with the possibility to scale them (with locked ratio). Dream-solution-B: a value can be entered for the largest object-dimension - if it's set to "square" that value will be used for both dimensions.

No update on area change

I just rectangled an area, generated and exported the stl. I then noticed, that the centered city was way off (that's another issue...) and shifted the rectangle sideways (and saved the change). I then re-generated the stl (it was much faster than the first time) and downloaded the new version - same filesize, strange. I then noticed that it was the exact same model! Conclusion: the edit-rectangle-tool does not change the generated model, it does not re-generate but takes the previous data.

feature request: display version-number in app

Pls display the app's version number in e.g. the "About"-window. When testing it I refresh the page but I can't be sure if it's properly reloaded or if I have to flush my browser cache. Having a version number would be great to verify.

Z-value slider too sensitive

The slider to set the Z-scale is a bit too sensitive. Trying to set that value to e.g. 4 takes several attempts. How about limiting it to .1-steps or implement a kind of snap-to-integer?

edge between 3d-surface mesh and side triangles not connected

Two sides of the output STL file seem to have issues with open connection between triangles of the 3d surface mesh and the side triangles. See e.g. this screenshot:

PreView

The handling is a bit akward because of the different projections. If I want to have a 3x3 tiled squared model I first have to output it untiled to check if the wanted area is correct. I have to do this several times because there are two stages of "blindness": first the selected area has a different ratio on the map-screen then on the object, second the squared-mode alters the selection. When this procedure is finally done I can switch to 3x3 and output the final model. This workflow is soooo annoying! Isn't there a way to create a kind of preview? Some outlines on the screen-map to see the resulting ratio & area would be most helpful. I know about the different projections but there has to be a way to calculate this beforehand. A model-viewer to see the computed model in low-res would be great but I guess a lot of users would mistake the low-res-preview for the final model.

Geometry simplification

There are now a lot of controls to modify the output except one: the simplification-voodoo you do with that geometry. I exported a large area first and then a smaller part from that area as a second model. I noticed that the smaller area resulted in a larger file = higher resolution. That's great on one hand (great details on the small one) but bad on the other hand (lack of detail on the large one). And yes, this makes sense if the object would be printed in one piece (print resolution) but my plan is/was to export a large area and cut that into smaller parts to print (like the suggestion I made earlier) - but with the lack of detail this is pointless :(

How about a Geometry Compression-slider to let the user decide how fine the resulting model will be created? Maybe with an estimation of polycount & file size displayed?

feature request: draw area from center outwards

I rectangled an area and tried to do it as square as possible. I enabled "square output". On the resulting model the desired center was positioned too far to the right.

I wonder if it's possible to draw the rectangle from the center outwards (not from corner to corner) and make that center on the map stay the center on the model.
