CAD/D Home > MicroStation > Raster Files in v8

Raster files should be attached to the 12345-Raster.dgn.  This file has 2 separate models, Aerial and Plan for raster file attachments.  USGS Topo Quads, DOQ Aerial Photos as well as High Res Aerials should be attached the the Aerial model and any plan files from previous projects or site plans for individual parcels should be attached to the Plan model. These files are only available to NHDOT personnel.

Pictures from each bureau should be attached to the Photo drawing created in that bureaus directory.  The N:\cadd\pbt\town\project number\Cadd\ directory contains a folder for each bureaus drawing \BrD\12345pxb.dgn, \Hwy\12345pxh.dgn,   ….and so on... When attaching pictures and other tiff files that don’t have a geo reference file the Place Interactively box should be checked.  If the file has an associated TFw file with it the Place Interactively box should be unchecked.  Attach all Raster reference files with the Open Read-Only box checked.  This will save having a box pop up asking you to save changes to a raster attachment you didn’t even change.

Aerial photo data has been moved to a new location (May 2011) on the recently implemented "N" drive. If you do not presently have an N drive, see the documentation for creating that. Current drive mapping includes G= \\Hzndotfile1\Global\, N=\\dot\apps\ S Hwy= \\Hzndotfile1\SB34\, V= \\dot\data\Images\

High Resolution Aerial Photos (2010 series) "Mr. SID" Version

Aerial images are now available in a new format - Mr. SID. SID files are nearly identical to the TIF files formerly used, yet only 5% of the size. If you need to attach more than a few aerial photos, this option will probably meet your needs while using much less of the computer's memory to display the files.New Hampshire state map They are stored in N:\Aerials\2010\ Statewide 1 ft MrSIDs\.

Note that these files are only available to internal NHDOT operators. Consultants working on NHDOT projects who wish to have copies of the images in the area of their project should send a request to their project manager at NHDOT.

To see which files are available in your project area, attach N:\cadd\cadd\GIS_To_MicrostationV8\aerial2010_mr-sid.dgn as a reference file. Be sure to select the Coincident-World orientation when attaching the file.

Files available for the desired area will be indicated by a rectangle with the file name. The text contains the name of the file. For example: 0900002250 refers to the file N:\Aerials\2010\Statewide 1 ft MrSIDs\0900002250.tif

To attach the photo in MicroStation v8i, use PowerSelector to select the area you want included. Make sure the various SID file name of each aerial photo you want included is in the area selected. It doesn't matter if other elements are also selected. From the NHDOT menu, select Attach Sid. This will locate and attach the desired aerial photos based on the file names selected. It may take a moment for the images to display.

To attach the photo in MicroStation v8 (2004 edition), open the raster manager (FileRaster Manager). Then select FileAttach… from the raster manager dialog box. Uncheck the Place Interactively box if it is checked. Navigate to the directory where the files are stored (or paste N:\Aerials\2010\Statewide 1 ft MrSIDs\ hit <tab>) and select the desired file.

If the image does not display in the proper location, check your user preferences. Select Preferences from the Workspace menu. Then select the Raster Manager category followed by the Georeference tab. Make sure that the Default Unit Settings are US Survey Feet, not meters. Change the setting to US Survey Feet if necessary and try attaching the image again.  To Top

High Resolution Aerial Photos (2010 series)

Much of the state was flown in 2010 to obtain updated aerial photographs. Some of these high-resolution aerial photographs are available to NHDOT MicroStation users. They are presently stored in N:\Aerials\2010\Statewide 1 ft\.  It is recommended that you use the SID files instead. The SID files are much smaller and are just as good.

Note that these files are only available to internal NHDOT operators. Consultants working on NHDOT projects who wish to have copies of the images in the area of their project should send a request to their project manager at NHDOT.

To see which files are available in your project area, attach N:\cadd\cadd\GIS_To_MicrostationV8\aerial2010.dgn as a reference file. Be sure to select the Coincident-World orientation when attaching the file.

If files are available for the desired area, a rectangle with the file name will be displayed. The text contains the name of the file. For example: 0900002250 refers to the file N:\Aerials\2010 Statewide 1 ft\\0900002250.tif

To attach the photo in MicroStation, open the raster manager (FileRaster Manager). Then select FileAttach… from the raster manager dialog box. Uncheck the Place Interactively box if it is checked. Navigate to the directory where the files are stored (or paste N:\Aerials\2010 Statewide 1 ft\ hit <tab>) and select the desired file.     To Top

DRG's and DOQ's

Geo-referenced TIFF files with the associated TFW files for USGS DRG Topo quads and DOQ Aerial Images are available to be used as raster references in MicroStation for NHDOT users. The index of sheet numbers for DRGs and DOQs can be found at N:\GIS\GIS_Users\Published_Maps\Aerial _Tiles\doq_Index_051702.pdf.  Sid files of aerial images are found in \mrsid sub-directory.  The sid files are approximately 50 times smaller and will load faster but suffer slightly in quality.  
USGS DRG directory - N:\GIS\GIS_Users\Data_Source\USGS DRG\ 
Aerial DOQ directory - N:\Aerials\Archive Imagery\1998 DOQ B&W\
 Each of the aerial and quad .tiffs have a corresponding .tfw file ("world file") containing the proper coordinates and scale in feet.  When attaching these raster files to a drawing, MicroStation can be directed to use the world file to correctly locate the image.  Some general instructions/settings are as follows:
  1. In MicroStation, under Workspace > Preferences > Raster Manager, make sure the "File Georeference Has Priority when Raster Is Loaded" box is unchecked.
  2. Set the "WorldFile Default Unit" to Feet.
  3. Finally, a key-in is required prior to attaching them.  Utilities>key-in> Enter or copy/paste RASTER SETCONFIG USEGEOTIFFSISTERFILEON.

Trent's Preferences panel

To attach the desired file, select Raster Manager from the File menu. Select Attach, uncheck the Place Interactively box if it is checked, then copy one of the above file paths into the dialog box to open the directory and then select the desired file.  These files should come in correctly and do not need to be scaled or rotated.     To Top

NAIP 2003 Color Orthos By County

Color Aerial Photographs of each county are available. They are not as detailed as the DOQ files, but cover a larger area, include more recent information, and are in color. The files are stored on the GIS server, the full file path location should be used. (N:\Aerials\Archive Imagery\2003 Statewide 1 m NAIP\) here you will find a separate directory for each county. Within the county directory is an image file (.sid) containing the aerial for that county.

In MicroStation, open the File>Raster Manager. Then select File>Attach from the raster manager dialog box. Paste the file path from above into the box hit <tab> and navigate to the county directory where the files are stored and select the .sid file. Check the Place Interactively box, select two points to define the location of the aerial photo. Don't worry about where it is placed, it will have to be moved. Double-click on the file name in the reference manager to adjust the attachment settings. If you used the Place Interactively option, the pixel size will need to be adjusted. Set this value to 1 for metric projects and 3.280840 for Imperial. If the rotation is not 0, then set it to 0. This value seems to vary between 2 and -2 depending on where in the state the project is located. Click the OK button to confirm these changes. 

Select the Move option on the Edit menu of the raster manager to move the photo to the project location. Repeat as necessary to get it to the correct location. The rotation may need to be adjusted. Set a fence around the area that is to be used for the project and then select the Clip Fence option from the Edit menu to crop the image. You can use the Warp option on the Edit menu for any additional adjustments.     To Top

Old Project Plans

The information below is a summary of the most common Raster Manager functions. Refer to the Raster Manager Guide for more details (MicroStation Help > Contents > Raster Manager Guide).

Select the Raster Manager Overview for a summary.

Select Raster Manager Tools for more details about raster file control and manipulation.

Old project plans are scanned and saved as .tif files and can be found in \\V:\Projects\HTML-Templates\rptPlanInventoryTown.html.  These files can be copied into a \Raster folder under the \prj directory and then attached to the 12345-Raster.dgn Plan model. 

Attach Raster Reference panel

To attach a cut sheet raster image, in MicroStation, open the raster manager (File > Raster Manager). Then select File > Attach… from the raster manager dialog box. Check the Place Interactively box if it is unchecked. Navigate to the directory where the files are stored. Select the appropriate file and add any logical names or description information. Click the OK button and click a spot on the screen where the sheet is to be placed and drag in the x direction, typing 1800 (36" sheet x 50 1"=50') into accudraw.

The display of the raster image can be modified by commands on the Raster Manager's Edit menu. Select the file you wish to alter and then the desired editing command. This does not alter the image, only how it is displayed.  Use the move, scale and rotate commands to position the drawing as appropriate.  The all.dgn can be used a base drawing as well as aerial photos and project detail to line up old plans.

Edit menuModify - a combination of the Move, Scale, and Rotate options

Move - change the location of the image on the drawing

Scale - make the image larger or smaller

Rotate - change the orientation of the image

Mirror - invert the image

Warp - using a group of "from" and "to" positions the image can be reshaped. This would typically be used when attaching images of scanned project plans to align them with the surveyed features.

The Clip option can be used to crop the image so only the desired portion is visible.Raster Control button menu

The Raster Control Tool Box can help greatly when working with raster files.  The raster selection tool makes finding a specific raster much easier.

Once these files have been scaled, moved and rotated this position can be saved.  A .tfw file is created as part of the Save As command.  You can save over the tif file that you copied into your project directory or save to a new location.  As long as the .tfw file is in the same directory, the .tif file's settings are saved.     To Top
