geotiff / geotiff.io Goto Github PK

Can we make it so that geotiff.io can be loaded when there's no internet connection?

I was able to draw multiple boxes with mode. I'll investigate and give repro steps later.

Sometimes if a user wants to embed geotiff.io with a tool and layer pre0loaded in their application (e.g. online lesson), they don't want the panel there. This is especially the case on mobile or tablet. We should have a param that you can put in the url to hide the panel at the very least.

Not sure if users should be able to unhide it...

Use Sweet Alert to notify user if can't pull in geotiff from url because of CORS restrictions. And tell the user to download the raster first :/

Is it possible to script the script loading, so that, for example, d3.min.js fails to load from unkpg, we then try another CDN. Code's also already super reliable, but this would take it to the next level. Or maybe, host all the node modules ourselves, but only call them if unkpg or other CDN's fail. They exceedingly rarely fail, but it would be nice to have a backup.

Zoom to GeoTIFF location button?

Let's users know that the website is working, but just takes some time to load a raster.

First read first chunk of bites to get metadata including compression algorithm

Then calculate what bytes we need to read in order to get value of pixel

User can enter Polygon as GeoJSON or draw area

Here's a list of cool libraries to check out and see about integrating:

• https://gitlab.com/IvanSanchez/Leaflet.TileLayer.GL
• https://github.com/drewbo/raster-histogram
• https://github.com/mapbox/tilelive-pixelmatch

Have user select an AOI and then automatically clip all rasters by that AOI when loading. Perhaps store AOIs in the browser cache / cookies. Or have ability to draw or paste GeoJSON.

To focus user attention

Include "add red outline" around GeoTIFF extent

It should label each pixel in the image

User said we should replace identify pin drop because it makes it looks like it's a point, not a pixel. How about instead of a pin, draw a red square around the pixel?

@sdpeyton, thoughts?

http://kripken.github.io/emscripten-site/

Have look at pixels and see number of possible classes.. Determine if discrete. Look at number of bands.

"Add GeoJSON"
"Add Shapefile"

Values inside still appear to be correct though

Explore this. Maybe create Pyramid in the browser. Use GL. Understand D3 and Leaflet code

Use sweetalert w some custom styling. Should appear when click things haven't dev'd yet like create a lesson

Should we round Mean: 121.97727272727273?

Or at least put that bar over infinitely repeating fractions?

Like make .333333 with the bar over the number 3

Is it possible to create a Google Chrome extension that will allow you to load remote rasters even without CORS enabled?

When users go to website for the first time, they might not know what a geotiff is or might not have one handy. Have a good one there ready for them to use and try out!

If someone tries to add a URL with an FTP schema, the app should alert that user that this won't work because browsers don't allow FTP

For example GLCF SRTM Degree Tiles

If we try to fetch the GeoTIFF and there's an error like 404 or CORS, need to tell the user why it failed, so they don't have to open up the console.
