Add local data such as geodatabases, shapefiles, KML/KMZ, GPX, and raster formats (JPEG 2000, GeoTIFF, MrSID). You can also add layer files and packages created using ArcGIS Desktop, or add locations from your spreadsheets.
This is done in order to save a little image space, although the savings should be minimal if JPEG or similar compression is used. After overlaying the image you may wish to view it with North pointing more conventionally.
JPEG compressed
The standard developed by the Joint Photographers' Expert Group features a high degree of compression while maintaining image high image quality (when viewed with the human eye). JPEG images work very well with photographic data.
A contour or topographic map first is scanned, and the image is saved in a raster image file format such as TIFF or JPEG.
Currently, two varieties of raster image formats are widely supported on the World Wide Web: CompuServe's popular Graphic Interchange Format (GIF) and the Joint Photographic Experts Group (JPEG) based format JFIF.
Raster data is stored in various formats; from a standard file-based structure of TIF, JPEG, etc. to binary large object (BLOB) data stored directly in a relational database management system (RDBMS) similar to other vector-based feature classes.
The current wave of GIS software for Internet is based either on the file downloading paradigm, or on the picture paradigm (presenting a map as a JPEG picture), ...
For example, JPEG compression uses Fourier transformation of small square pieces of a digital image.
TIFF 4, JPEG). Most scanning systems provide software to convert raster data to a vector format differentiating point, line, and area features.
When finished designing your map, you can export them as any type or format you wish, e.g. JPEG, PNG, etc. You can choose the resolution, and other exporting options.
