Answered my own question kind of... Export or convert raster datasets ArcGIS 10.3 Locate topic There are two main ways to export or convert raster data to another format. You can export raster data from within ArcMap by using the Export Raster Data dialog box or using a geoprocessing tool. The dialog box allows you to export a raster dataset or a portion of a raster dataset. Unlike other raster import or export tools, the Export Raster Data dialog box gives you additional capabilities such as clipping via the current data frame area, clipping via a selected graphic, choosing the spatial reference of the data frame, using the current renderer, choosing the output cell size, or specifying the NoData value. In addition, you will be able to choose the output format for the raster dataset: BMP, ENVI, Esri BIL, Esri BIP, Esri BSQ, GIF, GRID, IMG, JPEG, JPEG 2000, PNG, TIFF, or exporting to a geodatabase. Note: If you export your data with the Selected Graphics (Clipping) option, your image extent will be the union of your selected graphic and the extent of the raster. The second way to export or convert raster data is using the Copy Raster tool. There are many different raster dataset formats, which are normally differentiated by their file extensions. You can store your rasters in a file-based system or a geodatabase (personal, file, or ArcSDE). ArcGIS is able to view many different raster file formats, but it is only able to output a raster dataset as an Esri BIL, Esri BIP, Esri BSQ, Esri Grid, BMP, ENVI, ERDAS IMAGINE, GIF, JPEG, JPEG 2000, PNG, or TIFF format. When you name your output raster dataset, specify .bil for Esri BIL, .bip for Esri BIP, .bmp for BMP, .bsq for Esri BSQ, .dat for ENVI, .gif for GIF, .img for ERDAS IMAGINE, .jpg for JPEG, .jp2 for JPEG 2000, .png for PNG, .tif for TIFF file format, or no extension for an Esri Grid or a raster dataset in a geodatabase. When exporting your data using a selected graphic to a file-based raster dataset, it is recommended that you enter a NoData value. When a graphic is used to clip your data, NoData pixels will most likely exist in the output. Specifying the NoData value will allow you to control the pixel depth and the value that will store NoData. If a NoData value is not specified, the program will find an empty value to use as the NoData placeholder, which may not be desired or expected. You can also export or convert your raster data (raster dataset or mosaic dataset) into tiles, rather than a single raster dataset, using the Split Raster tool or the Raster To DTED tool. The Split Raster tool allows you to tile the output according to a tile size or number of tiles, among other options. The Raster To DTED tool will tile the output according to predefined DTED level schemas.

Program: ArcGIS 10.3 Need: Trying to get a free basemap for georeferencing a historic map so that I can overlay it in my project area. Attempted to use ESRI's USGS National Basemap so that I could georeference a scanned historic map to overlay in my project area. Problem Encountered: Using a work computer. Have both a stand alone liscense as well as a Citrix based liscense. Regardless of what liscense I use, my systems are being bogged down by two seperate server security settings and however long it takes for the ESRI server to get my basemap loaded so that i can set the reference points. 15 minuten wait at various scales. Strategy: Tried to find a different free basemap that I could use to finish the georeferencing process Data Mining: Looked for free USGS 7.5 minute quads. for California (DRG or spatially referenced anything will do as long as I dont have to pay for it). The only thing in found was the USGS websites (free GeoPDF's). Ended up converting thoste to .tff (not sure if the conversion process is part of the problem). Strategy: .tff converted to a .lyr through conversion and export option. Also created statistics in hopes of filling in any spatial referencing points that might have gotten missed with multiple conversions. .lyrs were brought into the 10.3 environment but provided an error message: 000840 : The value is not a <value>. Description The value specified is not a correct input parameter for that particular tool. Solution Set the parameter to a value or field or file of the type specified in the error message. Tried to set the parameters in the Environment settings but not sure if I did it correctly. Regardless, Same error message occurs. 000840 : The value is not a <value>. Description The value specified is not a correct input parameter for that particular tool. Solution Set the parameter to a value or field or file of the type specified in the error message. Help!! Any thoughts or old fashioned know how?

Sorry, Once I get the error message it defers me to the availible template page in access,

It gives me the below error message and then takes me to entry page for access as if it is blank....I am wondering if it is blank?

Re: Landscape template opens as portrait

trying to convert a .tff to a .lyr so that I can clip it. The .tff was originally a geopdf....or does anyone know where I can get free collerless USGS 7.5 minute quads for california.
