All the advanced georeferencing, digitizing, coordinate
conversion, and mapping features you need in a low-cost, unbelievably
versatile program. This is the ultimate geoprocessing and data
conversion tool for any map maker, cartographer, geologist, oil and gas
professional, or GIS analyst.
There has never been a more
comprehensive, powerful, all-in-one data conversion software solution
that provides an easy-to-use and intuitive user interface for
digitizing, georeferencing, coordinate reprojection, tiling, and
creating image mosaics. Didger solves the problem of
combining data files in different file formats and in different
coordinate systems, by providing extensive tools to transform your GIS
data into one cohesive coordinate system.
You can use Didger to precisely convert paper maps, graphs,
aerial photographs, well logs, or any other plotted information into a
versatile digital format that you can use with other software. Didger
can create new maps from the ground up or edit any existing map,
drawing, image, or data set imported into it.
Uses for Didger:
Start processing your data quickly and accurately with Didger. Some applications for Didger include:
-
digitizing points, polylines, and polygons, such as oil and gas wells,
wireline logs, graphs, contour lines, aerial photographs, satellite
images
- georeferencing and/or mosaicking aerial photos or scanned images
- overlaying vector, data, and image files to create a complete map
- calculating areas of polygons, such as watershed or lake areas
- calculating lengths of polylines, such as shorelines, roads, streams, or migratory routes
- and much more!
Digitizing Options:
The
process of creating new digital information often starts with a paper
map, graph or log, or a digital image such as an aerial photo, satellite
imagery or scanned paper map. Didger provides an easy and complete
solution to digitize vector data from your source documents and files by
using a powerful set of manual and automatic tools.
Versatility:
Didger
5 is tremendously flexible. Didger supports over 90 import file formats
and exports in over 45 file formats to make sure you can import and
export your data in the formats you need. Create large overlays easily
by importing several vector, data, or image files into one project. The
files will align according to their coordinate systems.
Working with Images:
Images
are powerful visualization tools, whether they are aerial photographs,
scanned geologic maps, or company logos. Didger makes working with
images simple and uncomplicated.
Easy Image Georeferencing:
Didger’s
fast and easy georeferencing process makes it possible to rapidly
convert un-referenced images and scanned paper documents to real world
coordinate systems (e.g., UTM, State Plane, Latitude/Longitude) for use
in Didger or other GIS programs.
Vector Based Maps & Data Files:
With
Didger you can import a variety of vector based maps and data files in
many formats. Create large coverages easily by importing several vector
or data files into one project. The files will align according to their
coordinate systems.
Projections, Datums, Coordinates:
Didger
makes it easy to assign or change the projection and/or datum of your
data, vector, or image files from one coordinate system to another. For
example, in a few simple steps you can convert latitude/longitude data
to State Plane data, State Plane data to UTM data, or convert your data
from NAD27 to NAD83.
Surfer Compatible:
Now
it is easy to see your maps the way you want them! Automatically
digitize contour or other 3D data in Didger and send them directly into
Surfer with a click of a button to change contour properties, overlay
with 3D terrain surfaces, DEM files, or other 3D imagery.
Advanced Editing Features:
Didger is packed full of advanced editing features designed to make your job faster and easier.
Supported File Formats:
Many
sophisticated import and export filters come with Didger, simplifying
the transfer of your data and images to and from your other
applications.
Note on Digitizing Tablets:
Nearly
all digitizing tablets work with Didger. If you already have a tablet,
Didger requires a 32-bit WinTab compliant digitizing tablet driver,
available from most tablet manufactures (for no charge) or from third
party vendors.
Here are some key Features of "Didger"
