Re: GIS support for Pharo

Stéphane Ducasse
Serge I was thinking that it would be good to create pharo-gis organisation. 
What do you and the others think?

GDAL FFI integration would be great, but this is a lot of work I guess.

Hi Serge,

I would love to participate in getting some GIS features into Pharo.  I think it would be a fantastic platform for GIS.

My personal orientation is doing marine navigation (have boat with sensors, want boat to be be smarter about navigation).

My main interests is in being able to render S57/S52 formats.  There are a number of boat fans that balk at the price of expensive chart plotter computers and software.

They have given rise to some DIY stuff.  Some of it just rips code straight out of https://gdal.org - I think possibly a FFI integration with gdal might be an amazing resource.

I am time constrained for when I can work on this stuff but would like it a lot if we at least had some core data types for simple things like lat/lng, regions (polygons), and a decent general map renderer.

Anyhow, please include me in any conversations.  Navigation (both air and sea) are two things I have an interest in.

Dear all,

there was already some discussion in the list about GIS support for Pharo previously.

Working on CORMAS multi-agent simulation platform: https://github.com/cormas/cormas some developers feel the need to have more GIS support for Pharo.

I know of existing GIS software:
- GeoJSON by Zweidenker: https://github.com/zweidenker/GeoJSON
- ESRI ascii raster, done by Stephane recently: https://github.com/Ducasse/ESRI-ASCII-Raster
- shapefile support by Hernan: http://smalltalkhub.com/#!/~hernan/Shapes
(to be moved to github)
- I found this project also: http://www.squeaksource.com/gekon.html

I know that Etienne Delay is also interested by GIS support and propose to implement OpenGIS model support: https://github.com/cormas/cormas/issues/139

Can we try to unite and maybe create a pharo-GIS organization on github to federate our efforts?

Cheers,

Cool can you fork my ESRI repo. I want to keep it for exercises in the future.
Or I can push it to this organisation and clone it for myself.

Yes sure. We will see how we integrate it to a bigger software.

Thanks Hernan!

 

I will try to find out what the problem is with your shape file.

 

Btw is the code for reading/writing dbf files already available on github?

Hi Hans,

 

 

El jue., 4 jun. 2020 a las 6:07, Baveco, Hans (<[hidden email]>) escribió:

Would be an interesting project..

An old link to possibly still useful code:

 

http://wiki.squeak.org/squeak/3317

 

 

Btw the shapefile support, from the ESRI spec, was done by me and is still available on http://www.squeaksource.com/@CUT95k_uXmPU4uXY/HCmgtrop.

 

Thank you for the clarification (and actually sharing your work with ESRI files!)

I added proper credits in the Github forked repo : https://github.com/hernanmd/Shapes

 

I use it daily. I may have some fixes/additions, but in general the code as provided works well (I suppose the code at smalltalkhub is still mostly the same). Some shapefile formats are still missing, mostly because I never encountered them..

 

You mean some types are missing? Because I get this error when I try to read some SHP files: "Types > 20 are not yet accounted for"

 

I wrote this script to reproduce:

 

 | shpE legend urlRoot urlESRIFilePrefix urlESRIFileShp urlPath response fileRef |

" Download Shapefile resources "
urlRoot := 'https://github.com/nvkelso/natural-earth-vector/blob/master/110m_cultural/'.
urlESRIFilePrefix := 'ne_110m_populated_places'.
urlESRIFileShp := urlESRIFilePrefix , '.shp'.
urlPath := urlRoot , urlESRIFilePrefix.

#('.shx' '.dbf' '.shp') do: [ : ext |
| url |
url :=  (urlPath , ext , '?raw=true') asZnUrl.
(response := ZnEasy get: url) isSuccess
ifFalse: [ self error: 'Cannot download file' ].
fileRef := FileSystem disk workingDirectory / (urlESRIFilePrefix , ext).
fileRef writeStreamDo: [ : stream |
stream nextPutAll: ((ZnByteEncoder newForEncoding: 'koi8r') decodeBytes: response contents ) ] ].

 

Once downloaded:

 

| urlESRIFilePrefix urlESRIFileShp shpE |
urlESRIFilePrefix := 'ne_110m_populated_places'.
urlESRIFileShp := urlESRIFilePrefix , '.shp'.

" Load and display it in Morphic "
shpE := ShapeEnsemble fromFile: urlESRIFileShp.

 

Maybe it's related with the fact they are encoded as koi8r?

I checked with Zinc downloading first from the browser:

 

| shpFile |                                                                            
shpFile := 'ne_110m_admin_0_countries.shp' asFileReference.
[ shpFile binaryReadStreamDo: [ : in |
                (ZnCharacterEncoder detectEncoding: in upToEnd) identifier ] ]
        on: ZnCharacterEncodingError
        do: [ nil ].

 

 

Cheers,

 

Hernán

 

To read a complete shapefile one also needs to read dbf files. This was another substantial effort http://www.squeaksource.com/@Y4HhnL90iyA2TmAb/X0sPqshM; luckily  there was an older implementation.available to build upon.

Not sure whether nowadays there are other ways to read/write files old DBASE format files...

 

Cheers,

 

Hans Baveco

Subject: [Pharo-users] GIS support for Pharo

 

Dear all,

 

there was already some discussion in the list about GIS support for Pharo previously.

 

Working on CORMAS multi-agent simulation platform: https://github.com/cormas/cormas some developers feel the need to have more GIS support for Pharo.

 

I know of existing GIS software:

- GeoJSON by Zweidenker: https://github.com/zweidenker/GeoJSON

- ESRI ascii raster, done by Stephane recently: https://github.com/Ducasse/ESRI-ASCII-Raster

- shapefile support by Hernan: http://smalltalkhub.com/#!/~hernan/Shapes

(to be moved to github)

- I found this project also: http://www.squeaksource.com/gekon.html

 

I know that Etienne Delay is also interested by GIS support and propose to implement OpenGIS model support: https://github.com/cormas/cormas/issues/139

 

Can we try to unite and maybe create a pharo-GIS organization on github to federate our efforts?


Cheers,
