  • Redesign geodata models to support non-spatial data

    Redesign geodata models to support non-spatial data

    Per team discussion, we need to support non-spatial imagery as well.

    I will brainstorm a new model hierarchy and post it here, then sync up with David about the implementation. I already have a few ideas about how we can make this work in a general fashion while keeping the SpatialEntry concept that informed our initial model design.

  • STAC Browser

    STAC Browser

    This imports version 2.0.0 of the STAC Browser. The build process was difficult to automate (a couple patches), so I made the decision to build and commit the result into the tree. STAC Browser 3.0.0 is the next release, so we can automate the build process there.

    The existing STAC-API was fleshed out a bit more to handle the browser.

    The STAC Browser is visible at /rgd_imagery/stac_browser/.

    Here is an example browsing the user's "default" collection:

  • Allow lazy random access to files in Storage on S3

    Allow lazy random access to files in Storage on S3

    When a Django FieldFile (the object referenced by a FileField) is opened, both in development with MinIO and in production with AWS S3, the Storage layers download a whole file write it to a SpooledTemporaryFile (which is in-memory for small content and on-disk for larger content)

    • S3Boto3Storage: https://github.com/jschneier/django-storages/blob/770332b598712da27ecdba75c9e202ad6a1a8722/storages/backends/s3boto3.py#L132
    • MinioStorage: https://github.com/py-pa/django-minio-storage/blob/8ce77cd8eae0d86fa3200e74cde64144c0338f37/minio_storage/files.py#L130

    However, many operations need random access to only a small part of the file's content.

    If all that's necessary is a Python file-like object (which is the same interface that a Django FieldFile naturally provides), we could look into developing a new Storage wrapper which lazily loads the content of the file-like object, internally using HTTP Range requests to only download the required parts just-in-time to be read from. This would likely also include some caching of the parts once they are retrieved.

    If external tools (like GDAL) need access via a filesystem path (i.e. what's provided by field_file_to_local_path), then FUSE may be the most appropriate abstraction. However, FUSE could not be run on Heroku and might generally be more difficult to install for new developers.

    In either case (Python file-like object or FUSE), the underlying logic for how to fetch and cache portions of file content may be the same.

  • psycopg2.errors.UniqueViolation: duplicate key value error

    psycopg2.errors.UniqueViolation: duplicate key value error

    When running the demo data commands that I have, if the celery worker is set up to run in the background, an integretiy error for duplicate keys happens on the image_entry.save() call here:

    https://github.com/ResonantGeoData/ResonantGeoData/blob/998a6c3995b4421c3632979a249fb78d66e1108f/rgd/geodata/models/imagery/etl.py#L69

    The error:

    Traceback (most recent call last):
  File "/usr/local/lib/python3.8/site-packages/django/db/backends/utils.py", line 84, in _execute
    return self.cursor.execute(sql, params)
psycopg2.errors.UniqueViolation: duplicate key value violates unique constraint "geodata_imageentry_image_file_id_key"
DETAIL:  Key (image_file_id)=(14) already exists.

    This is making me think that when we create a new ImageEntry in the tasks, there is some sort of race condition between jobs for the same ImageFile... which shouldn't happen? I'm not really sure what is going on here.

    Steps to reproduce

    1. Clear the database volume
    2. Apply migrations: docker-compose run --rm django ./manage.py migrate
    3. In one session, launch the celery worker: docker-compose up celery and wait until ready
    4. In another session, run the Landsat demo data command: docker-compose run --rm django ./manage.py landsat_data -c 3
      • Use the changes from #296
    5. Observe the error

  • Large image

    Large image

    Closes #260

    This is a simple tile server endpoint. It's not an app as was imagined. There's a 💯abstract™ app in 701293890f75b646d042da877289646ebac88a7f. It started feeling silly for just one endpoint, so it was reverted. It may be useful down the road.

    I didn't want to deal with the context manager to download/cleanup S3 files, so instead I'm using /vsis3/ and /vsicurl/. You can see the implementation in 8b4d2fc6f162447c128b1a4fdb17e8353853dd09. I think it's simpler and luckily results in a pretty quick tile server. It was tested with other ETL routines in ed9bd8ae57e3d9c9ff9f891847a051073280b2ce, which seemed to work fine, but that was reverted to stay on topic with this PR.

    New endpoints:

    • api/geodata/imagery/image_entry/<pk>/tiles: get an ImageEntry's metadata
    • api/geodata/imagery/image_entry/<pk>/tiles/<z>/<x>/<y>.jpg: get an ImageEntry's x, y tile at zoom-level z

  • Rgdc usability improvements

    Rgdc usability improvements

    This MR contains 3 small improvements to rgdc.Rgdc.

    1. Add 5 automatic retries on all GET requests. This is to guard against random 503 errors from rate-limiting that would be fixed by simply rerunning the command. The implementation is to bake this into the Session object; see https://www.peterbe.com/plog/best-practice-with-retries-with-requests for the approach.
    2. Add overwrite=False kwarg to download_raster_entry. This will skip files already on disk - handy for speeding up tests and making scripts idempotent.
    3. Perhaps a more controversial one: let download_raster_entry and download_raster_entry_thumbnail directly parse a dict returned by search to find the id, rather than the user having to make another request manually as in the README example or study that dict to find it. I believe this will improve usability for the current use cases, as the users of this client should need to know as little as possible about the internals of RGD's data representation (and web programming in general, for that matter) to get started. But I am open to ideas to implement this in a more principled and future-proof way.

  • fix thumbnails and outline geometry

    fix thumbnails and outline geometry

    Resolve #176

    For future reference, use the following example rasters to verify that the thumbnails are working.

    • LC08_L1TP_033032_20200422_20200508_01_T1_pixel_qa.tif
    • landcover_sample_2000.tif
    • vegdri_emodis_week34_082320.tif

    Summary of change:

    • new admin actions to reprocess image entries and raster entries (calls save to trigger save event and recreate the thumbnail or spatial reference)
    • added a helper method to reproject an open rasterio raster to a given ESPG
    • During image thumbnail generation routine: reproject raster to Web Mercator before extracting if the image file has a spatial reference
    • During raster outline/valid footprint calculation:
      • first, reproject the raster to the DB's spatial reference (something was off when transforming the extracted geometry)
      • use rasterio/GDAL to extract a mask and create the GeoJSON feature (as opposed to our own convex hull approach)
    • Raster detail view page now limits the view bounds on the map
    • Update centroids in the raster tests since we are extracting the geometry properly now

  • `yield_checksumfiles` function doesn't handle `ChecksumFiles` with file paths as their `name` correctly

    `yield_checksumfiles` function doesn't handle `ChecksumFiles` with file paths as their `name` correctly

    To reproduce, run this management script and then try to view the Raster that it creates. The tile requests will fail with 500 errors with errors about wrong file paths in the server log.

    I came across this bug when working on Danesfield. On that project we encode the file path of a given ChecksumFile inside the name column - for example, foo/bar/foobar.txt represents a file hierarchy of

    foo/
  bar/
    foobar.txt

    This line in RGD is incompatible with this approach, since it assumes the ChecksumFile name is a flat file name instead of a file path. For example, if we have a ChecksumFile with the name foo.tiff, the current code would work:

    path = '/tmp/rgd/file_cache/foo.tiff'
with yield_checksumfiles([self], path.parent):
    yield path

    Note that path.parent would be /tmp/rgd/file_cache/foo.tiff, which is correct. But if the file name is a/b/c/foo.tiff:

    path = '/tmp/rgd/file_cache/a/b/c/foo.tiff'
with yield_checksumfiles([self], path.parent):
    yield path

    the call to path.parent would evaluate to /tmp/rgd/file_cache/a/b/c, which is incorrect and leads to 500 errors since the server can't find the files in that location.

  • kwiver test failing

    kwiver test failing

    I cannot reproduce this error outside of the tox testing environment:

    https://github.com/ResonantGeoData/ResonantGeoData/runs/5993156571?check_suite_focus=true#step:7:60

    I added a skip for the failing test in

    https://github.com/ResonantGeoData/ResonantGeoData/commit/cd01ca20c99be4e69500d1bc1732b29a92c2214e

    The error logs are: stderr.txt

    the most likely culprit is

    terminate called after throwing an instance of 'pybind11::error_already_set'
  what():  ImportError: /usr/local/lib/python3.8/lib-dynload/_posixsubprocess.cpython-38-x86_64-linux-gnu.so: undefined symbol: PyTuple_Type

    I cannot figure out why this is all of a sudden failing - no obvious packages have recently been upgraded

  • Persistent S3 test file

    Persistent S3 test file

    We need a persistent file on S3 to test our file handling.

    At present, we have the following fixture:

    https://github.com/ResonantGeoData/ResonantGeoData/blob/f41be685481d3f62457aba1001faa68012760ffc/testing-utils/rgd_testing_utils/data_fixtures.py#L51-L53

    but that is currently failing with object nor found errors.

    This is not the first time this has happened and I've updated that fixture. I will temporarily patch this with another file from that bucket, but we really need to find a file, any file on S3 that we can rely on persisting.

  • migrate collection to FileSet

    migrate collection to FileSet

    • [ ] Add concrete definitions for all models in rgd and rgd_imagery
    • [ ] Make sure no two images point to the same FileSet (ref #591)
    • [ ] Change ancillary_files field on Raster to be a manyToManyField to FileSet
      • [ ] make sure this fileset is not used for an Image
    • [ ] add annotation on Image to point to FileSet
    • [ ] Change all relationships to ChecksumFile to point to FileSet per new definitions (Image is the exception and will be well documented why)

    Other things to address/start thinking about:

    • [ ] How does a user upload data? First, create a FileSet, then add ChecksumFiles? how do we implement that in the REST endpoints and Python client cleanly? Can we add some server-rendered pages to handle make this easier for users?
    • [ ] when getting images from an ImageSet, check each Image's FileSet collection before yielding
      • think of the use case where two users privately uploaded processed imagery to that ImageSet (through the ProcessedImage models)

    initial prototyping done in #566

    Title: Making a Schema Crosswalk between Django Models and STAC API

    Description: Kitware offers ResonantGeoData: a Django web application for visualizing and searching geospatial datasets. We added support for interacting with these datasets via the STAC API. This lightning talk will discuss how we made a schema crosswalk from our current API and data models to comply with the STAC API.
