Raster Loading Instructions



Raster Data will be loaded in the GeoPortal instance of SDE (VM68)

The format for most raster loads will be jpeg2000 or .jp2.



Using ArcCatalog

Convert the raster into the desired format. Use JPEG2000, at 75%. Rasters cannot be converted

to other formats once they have been loaded. Also, if the raster is being compressed, a smaller

file is being loaded to the server. Large rasters will often fail to load, check the loading logs to

monitor for errors. Preprocessing has two steps; check for a world file and convert the raster

format.



A. Creating .tfw (world files)



If you know the pixel size and coordinates of a large set of tif files, you can quickly generate a

set of world files to go with them. In a spreadsheet, create a sheet that has Name, X-pixel size,

Y-pixel size, Longitude, and Latitude in decimal degrees. Save this as a .csv to serve as input to

auto_georef.exe. Run auto_georef and put the .csv file name in the first box and an output

directory in the second and click "write files". The .tfw file will be written to the directory.



World files for tifs, tfw, are identical to those for jpgs, jpw. They have the form

-5.5145177916482861e-007

78.4634327622498

17.4016286081658

Where the longitude and latitude are the upper left corner of the image (at least in the Northern,

eastern quadrant).



B. Converting the format.



Navigate to the file in ArcCatalog. Right-click and choose "Export --> Raster to Different

Format...". Enter the appropriate extension for the new format into the "Output Raster Dataset"

text box. The extension for JPEG2000 is '.jp2' . Click 'OK'. ArcCatalog should create a copy of

your raster in the new format.

Once the raster is in the desired format, it may be imported into the Geoportal dataset. Right-

click on the Geodata Repository ( "GISOWNER01@gisportal@VM68.atech.tufts.edu.sde" ) and



C. Import the Raster.



Select "Import --> Raster Datasets...". Navigate to find the input raster. Click the

"Environments..." button at the bottom of the dialog window. Click "Raster Storage Settings"

and scroll down to "Compression". Select the appropriate compression ( JPEG2000 ) and

compression quality (75). Click "OK", then "OK" again. The raster will be imported into the

Geodata Repository with the specified compression. If it is a single image and not a mosaic,

check calculate statistics, add colormap and build pyramids( as necessary).

Metadata must still be loaded into the metadata tables so that the raster is accessible to users.

Grant 'SELECT' privileges to SDE, GEOSERVER2x by right-clicking on the layer in the

Geodata Repository and selecting "Privileges". Type "Geoserver2x" in the text box and click the

check-box next to "SELECT. The user may query the selected object(s) data." before clicking

"OK". Repeat this for “SDE”



Using the Command Line

1. Create a list of the files to import

a. Create a text file listing all of the layers

i. Open a command prompt

ii.Change directory in the command prompt Type

cd M:\datasets\State\MA\MassGIS\Imagery\Orthos2008\15cm_mosaics



iii. Type "dir /M *.sid > layers.txt" (.sid is the file type, change this to .tiff or .jpg as

appropriate). This will create a text file called layers.txt in that directory that lists all of the

metadata files.

iv. Edit the text file or excel file so that you have an sderaster command for each layer



as Text

sderaster –o import –l ,image –f .jp2 -g -G -i

geodata -s sde:sqlserver:vm68.atech.tufts.edu -u gisowner01 -p >

C:\Logs\LoadLog.txt



sderaster –o import –l US_MA_MetrowestOrthos_2008 ,image –f

M:\datasets\State\MA\MassGIS\Imagery\Orthos2008\15cm_mosaics\metrowest1.jp2 –N

–c jp2 –g -G 102686 –L 0 -i geoportal -s sde:sqlserver:vm68.atech.tufts.edu -u

gisowner01 -p > C:\Logs\LoadLog.txt

( Building the pyramids and colormap after the load)



1a. When building Mosaic, after the first line,all the following lines should mosaic the

images to the first image

sderaster -o mosaic -f metrowest2.jp2 -l US_MA_MetrowestOrthos_2008,image -v 1 -N -L 0

-Align -i geoportal -s sde:sqlserver:vm68.atech.tufts.edu -u gisowner01 -p >

C:\Logs\LoadLog.txt

If you use Excel to create the script save as txt

c. Change the .txt to.bat extension (i.e. import.bat)

d. Run the file from the command line



2) Check for errors

Open the loadlog.txt file and search for errors where the file did not full load. Check

the expected record count to the final record count.

Load input features into Spatial Index Batch mode, click on check mark If

Spatial Grid 1 has a number other than 0 a spatial grid is present. Delete any

layers that have a spatial grid in place then hit ok to generate new spatial

indices for the layers.





3) Define the projection

a. Copy import.bat to project.bat

b. Note the projection ID for each layer

i. Open the metadata file for the layer

ii. Find the name of the projection

iii. Go to http://spatialreference.org/ref/esri/

iv. Find the appropriate projection and note the numeric code example ESRI 102686

or EPSG:26986: for Massachusetts data

c. Edit each line to the correct command to define the projection

sderaster -o alter -i geoportal -s sde:sqlserver:vm68.atech.tufts.edu -u GISOWNER01 -

p -l ,footprint -G 102686 >> C:\Logs\projectionsLog.txt

d. Run the file from the command prompt



4) Build Colormap( as necessary)

sderaster -o colormap -l US_MA_MetrowestOrthos_2008,image -L -1 -v 1 -i geoportal -s

sde:sqlserver:vm68.atech.tufts.edu -u gisowner01 -p > C:\Logs\LoadLog.txt

5) Builds pyramids( as necessary)

sderaster -o pyramid -l in_hyderabad_g45survey_1915,image -L -1 -v 1 -i geoportal -s

sde:sqlserver:vm68.atech.tufts.edu -u gisowner01 -p > C:\Logs\LoadLog.txt



6) Calculate Stats for processing



sderaster -o stats -l US_MA_MetrowestOrthos_2008,image -v 63 -i geoportal -s

sde:sqlserver:vm68.atech.tufts.-u gisowner01-p [pwd]

----------------------------------------------------------------

Usage: sderaster -o stats -l -v

[-d] [-L ]

[-i | ]

[-s ] [-D ]

[-u ] [-p ]



-d Deletes image statistics and histogram.

7) Grant appropriate permissions



a. You are granting select privileges to users GEOSERVER2X and SDE

b. Open the project.bat file in Notepad or some other text editor

c. Save as grant.bat

d. Edit the commands in the file to be grant commands

i. Change the sderaster commands to read each of these users

sdetable-o grant -i geoportal -s sde:sqlserver:vm68.atech.tufts.edu -u

GISOWNER01 -p -l ,footprint -A select -U sde >

C:\Logs\permissionsLog.txt



sdetable -o grant -i geoportal -s sde:sqlserver:vm68.atech.tufts.edu -u

GISOWNER01 -p -l ,footprint -A select -U geoserver2x >

C:\Logs\permissionsLog.txt



ii. Note that the -o argument changes to "grant

iii. Repeat all of the lines, substituting "-U sde" for "-U geoserver2x"

e. Run the batch file from the command prompt



8. Rename ( As necessary)



sdetable -o rename -t -T

[-i ] [-s ] [-D ]

[-u ] [-p ] [-N]

[-q]

sdetable -o rename -t in_hyderabad_G45survey_1915 -T in_hyderabad_g45survey_1915 -i 5150

-s mapmaker.mit.edu -u sde_data -p [pwd]



9) Import layer metadata

Following the appropriate Metadata steps either in ArcCatalog or GeoNetwork . If no metadata

exists, start with Step 1 Standard Metadata Creation. If metadata exists, start with Step 2 Batch

Metadata Loading

a. 1_Standard_ArcCatalog_Metadata_Creation

2_Batch_ArcCatalog_Metadata_Loading

3_Checking_ArcCatalog_Metadata_



b. 1_GeoNetwork_Metadata_Creation

2_Batch_GeoNetwork_Metadata

3_Checking_GeoNetwork_Metadata



c. Enter user name (gisowner01) and password in the dialog box, then click connect

e. Make sure the proper options are selected for "Raster dataset" and "Publicly Accessible"



10) Rebuild indices

a. Open index.sql from the desktop

Or by Command line

AddSpatialIndex_management {spatial_grid_2}

{spatial_grid_3}

AddSpatialIndex_management Somerville_Buildings 4.1 16.4 0

b. Run each command separately. You do not need to edit anything.
