How to load tiles into Atlas

0. Scrape tiles (example) Run each command for different zoom

python3.6 scraper.py --poly polygon.json --zoom 20 --url "https://public-tiles.dronedeploy.com/000001_CAMPFIREMERGED_ortho_combined/{z}/{x}/{y}.png?Policy=eyJTdGF0ZW1lbnQiOlt7IlJlc291cmNlIjoiaHR0cHM6Ly9wdWJsaWMtdGlsZXMuZHJvbmVkZXBsb3kuY29tLzAwMDAwMV9DQU1QRklSRU1FUkdFRF9vcnRob19jb21iaW5lZC8qIiwiQ29uZGl0aW9uIjp7IkRhdGVMZXNzVGhhbiI6eyJBV1M6RXBvY2hUaW1lIjoyMTQ1OTE0OTU4fX19XX0_&Signature=fU7e86EFcMvXB13wV9u7HkBWleGnXG05T6jjMdzMaBXUIFhTAKmKubhSkZp9X8XrHEGC5WQR5XjN6fQEj7NAZweJmZCknyD7gb4IdwG3OZSP854Kp6l~XnS6NVjlIkm9c6XYvaGX80eOlOAQGGpsq3qrw5NT92emLQhs05aswW18kPxjW7N~V-Hx0c4bjsrtZ6I7z8Vo7EaHb4qa68vqKjdx31Xk2u96hf2rch6Qbsm4bAsc1HqjBP2os7c3r-W~7KbShzrcSY27MACqfMrbK0~fjPBl1qJOsLixOXK27JfWWUKazxhKcOtZDG74--j-sHoR33H~6VXT2pvzl9mJpg__&Key-Pair-Id=APKAJXGC45PGQXCMCXSA" --out-dir tiles --max-connections 4 --retries 10

1. Use pyramidize.sh tiles to create pyramid of tiles for the tiles scraped by scraper.py.
2. Upload tiles to S3 folder e.g.

aws s3 sync tiles s3://pylot/gis/cal/jon/code/odm_orthophoto/tiles/

3. Create UTM coords file.

• get one point coordinate from polygon geojson used to scrape the tiles
• Go to https://www.latlong.net/lat-long-utm.html and convert the coordinates to UTM format
• create coords.txt that contains:

WGS84 UTM 10N 
620372.17 4404507.85 

where

10N - zone
10N - If it's northern hemisphere - leave N
620372.17 - easting
4404507.85 - northing

4. Upload UTM coords aws s3 cp coords.txt s3://pylot/gis/cal/jon/code/odm_georeferencing/coords.txt

5. Create UTM bounds file.

• get polygon bounds (they are printed using https://github.com/unleashlive/xy2latlng) example:

[West, South, East, North] 
-121.59431, 39.78201, -121.58808, 39.786

convert to [topleft, bottomright]
[-121.59431, 39.786]
[-121.58808, 39.78201]

• Go to https://www.latlong.net/lat-long-utm.html and convert the coordinates to UTM
• best is to use 0 0 0 0

6. Upload UTM coords

aws s3 cp jon/code/odm_orthophoto/odm_orthophoto_corners.txt s3://pylot/gis/cal/jon/code/odm_orthophoto/odm_orthophoto_corners.txt

7. Add atlas asset:

• key - relevant path to pylot bucket
• code/odm_orthophoto will be appended

}

Optional 8. Upload additional layers such as geojson
