Examples:
s3://tnris-ls4/bw/Bexar/txdot_1956/index/georef/05-09-56_04-53.tif s3://tnris-ls4/nc/USDA/123456/frames/scanned/05-09-56_04-53.tif
-
scan frame as .tif as normal. save to the normal folder structure (Q drive?) in the normal organized location.
-
open the .tif in ArcMap and georeference as per normal instructions (saving separate world file as per normal procedures). typically, georeferencing with the most locale projection is most accurate.
-
then, with the georeferenced .tif in arcmap, export with the rules:
* `256` populated for handling the NoData field. * WGS84 Web Mercator (`EPSG 3857`) Projection These rules create and save a .tif with the proper projection, header information, and transparency for cells of no data. <em>Note: this process does create another world file (.tfw) but this can be ignored - we won't be using it</em>
-
Upload original, non-georeferenced scan to the correct “…/frames/scanned/” directory tree location.
-
Upload exported, georeferenced .tif from #3 to the correct “…/frames/georef/” directory tree location. Only the .tif needs to be uploaded; ignore the .ovr and all other associated files which are created in the process.
Note: since mulitple copies of a frame can exist as varying DPIs, the filename can include an "_<dpi #>dpi" suffix after the frame # but before the file format. Example: "<mm>-<dd>-<yy>_<roll>-<frame #>_<dpi #>dpi.tif"
SUPER IMPORTANT: uploaded mosaics must be split with each split tile raster named "mosaic<tile #>.tif" or the process WILL NOT WORK
-
Pull all the individual georeferenced frames into mosaic’n software (probably ERDAS).
-
Perform the mosaic’n functionality and export IMG.
-
Open the IMG export in ArcMap and perform Individual Frames #3 GeoTiff export with the same rules.
-
Open/Add the GeoTiff to the ArcMap session. You can remove the IMG also.
-
In ArcMap alongside the GeoTiff, bring in the ‘USGS_Quad16th’ shapefile from the ‘USGS Quadrangle Indicies’ download from tnris.org.
* Download here: https://tnris-datadownload.s3.amazonaws.com/d/usgs-indices/state/tx/usgs-indices_tx.zip
-
Select the quad 16th polygons which overlap the extent of the mosaic. Right click, and add to map as new Selection Layer.
-
Open the SplitRaster tool. Set the following inputs:
* Output Base: mosaic * Output Folder: <any empty directory where all the new cut/split up rasters can be dumped> * Split Method: POLYGON_FEATURES * Split Polygon Layer: <choose the selection layer created in step #6> * Format: TIFF * Resample: Nearest * Under Other settings dropdown section at the bottom, set NoDataValue: 256
-
The tool may take some time. The output folder will be filled with GeoTiffs for each USGS Quad 16th polygon. Each will be incrementally named: “mosaic<tile #>.tif” with an example being “mosaic12.tif” starting with number 0
-
When finished, upload all the exported georeferenced mosaic<tile #>.tif files from #7 & #8 to ‘the correct “…/mosaic/georef” directory tree location. Only the .tif needs to be uploaded; ignore the .ovr and all other associated files which are created in the process.
Note: Mosaics can get really large. They must be split in this method to properly run
SUPER IMPORTANT: uploaded indexes must be split with each split tile raster named “<originator>_<yyyy>_<sheet #>_<tile #>.tif” or the process WILL NOT WORK
-
Perform steps Individual Frames #1-3 as if the index is an individual frame.
-
Upload original, non-georeferenced scan to the correct “…/index/scanned/” directory tree location. This original should be named “<originator>_<yyyy>_<sheet #>.tif” since (as an original) it is not chopped up for serving.
-
In ArcMap alongside the GeoTiff, bring in the ‘USGS_Quad16th’ shapefile from the ‘USGS Quadrangle Indicies’ download from tnris.org.
* Download here: https://tnris-datadownload.s3.amazonaws.com/d/usgs-indices/state/tx/usgs-indices_tx.zip
-
Select the quad 16th polygons which overlap the extent of the index. Right click, and add to map as new Selection Layer.
-
Open the SplitRaster tool. Set the following inputs:
* Output Base: <originator>_<yyyy>_<sheet #>_ (Example: "USDA_1975_1_" without the quotes) * Output Folder: <any empty directory where all the new cut/split up rasters can be dumped> * Split Method: POLYGON_FEATURES * Split Polygon Layer: <choose the selection layer created in step #4> * Format: TIFF * Resample: Nearest * Under Other settings dropdown section at the bottom, set NoDataValue: 256
-
The tool may take some time. The output folder will be filled with GeoTiffs for each USGS Quad 16th polygon. Each will be incrementally named: “<originator>_<yyyy>_<sheet #>_<tile #>.tif” with an example being “USDA_1975_1_12.tif” starting with number 0
-
When finished, upload all the exported georeferenced <originator>_<yyyy>_<sheet #>_<tile #>.tif files from #5 & #6 to ‘the correct “…/index/georef” directory tree location. Only the .tif needs to be uploaded; ignore the .ovr and all other associated files which are created in the process.
Note: Indexes can get really large. They must be split in this method to properly run Note 2: since mulitple copies of an index can exist as varying DPIs, the filename can include an "_<dpi #>dpi_" after the sheet # but before the tile number. Example: "<originator>_<yyyy>_<sheet #>_<dpi #>dpi_<tile #>.tif"
Process output will be a WMS Service for each collection. The link will be:
http://mapserver.tnris.org/wms/?map=/mapfiles/<collection mapfile name>.map
Collection Mapfile Naming Convention (all lowercase with natural spaces supplemented with underscores):
<county name>_<agency name>_<yyyy>_<type>.map
– or –
<multi-county agency>_<mission code>_<type>.map
where type is ‘frames’, ‘index’, or ‘mosaic’
