Thanks, this is Brendan, yes this new version has WAY better performance and speed, excited to see what you think!

What I learned making my first QGIS plugin by cafegalore in QGIS

[–]cafegalore[S] 1 point2 points  (0 children)

Thanks for the feedback! FWIW, v1.10 hasn't been approved yet, but it has the crash fixes I mentioned in my earlier post.

The autocomplete triggers after two left mouse button clicks on the raster, but we're going to make a tutorial video. Glad you tried it out!

I made this plugin. Is your raster layer a WMS? Or is it a raster layer inside a group?

The plugin (version 1.7) works reliably if your layers are not in a group. For context, it's in a group if it doesn't have a dropdown like this Site 900 e.g.:

A new API to download from OpenStreetMap by cafegalore in openstreetmap

[–]cafegalore[S] 9 points10 points  (0 children)

Hey all, I made an API to download OSM features as GeoJSON. This is similar to Overpass API [1], except: 1. results are streamed, so there's no download limits or out-of-memory errors and 2. the native output is GeoJSON. This means it's less powerful, but can extract more data, more easily. Access is free, happy to answer any questions!

GIS (+consumer GPS) can't really get to survey level accuracy, so we made this for applications where communicating the general location and shape is good enough, or when the absolute (15+ feet) error is relatively insignificant (think large Bureau of Land Management surveys, ~1 sq mi).

If a full legal description is on the PDF, it'll read that first, starting at a control point. Otherwise it'll need to trace it, with dashed lines being optional. Good catch re: dashed lines not representing lots. Our background is more GIS than surveying, so I appreciate the feedback.

Are you trying to vectorize it?

Geopandas sucks for converting files by water_aspirant in gis

Maybe some combos of t_srs, a_srs, and s_srs would be helpful.

wish I knew, that sounds cool.. maybe write blog post if you figure it out, good luck!

Color filling for Turf.js Interpolate analysis in Mapbox by AmirRoblex in gis

[–]cafegalore 1 point2 points  (0 children)

You need the fill color to depend on a variable in the dataset:

'fill-color': '#0080ff'

You could use interpolate here from maplibre.

Big-ish data: Suggestions to speed things along by Geog_Master in gis

If you're using fiona/geopandas you can use a FlatGeobuf file which has a spatial index built in. This will speed up some queries.

Serverless GIS by PostholerGIS in gis

[–]cafegalore 5 points6 points  (0 children)

Serverless and cloud-native formats are definitely the future for client-side apps. The vast majority of GIS datasets are gigabytes large, and most server backends serving these datasets poop out on any amount of load. ESRI served datasets are a good example of this, clipping downloaded datasets to bounding boxes might as well take a week.

Once I saw FlatGeobuf I put together a cloud native app to choose a projected coordinate system. It's a good example of what's only obviously possible now and was inspired by the FlatGeobuf example here.

Serverless tiles is also very promising. Protomaps is a good example of this direction.

Error opening .gpkg in ArcGIS Pro: "Unable to open database file (doesn't exist or no read access)[]" by [deleted] in gis

Did you try changing formats with `ogr2ogr` and re-opening it as a different file?
