Images

InFoCAD has several features to further enhance the functionality already included in the product. These features are designed with the same intuitive user interface and enable specialized capabilities in specific area such as: Raster Data, Raster Data Conversation, Non-Graphic Database Access, and Low-Cost Data Entry & Retrieval.

Image Display & Management

GIS today requires both vector and raster capabilities. To meet this, InFoCAD provides InFoIMAGE, a powerful, fully integrated optional feature with a unique interface. The commands in InFoIMAGE allow users to calibrate, rectify, crop, and display raster images of any size or resolution, as well as play or run video files.

InFoIMAGE classifies al images into two types: primary and secondary. Primary images are images that are displayed in the background of the viewing area, and are commonly overlaid with vectors. Secondary images area images that are associated with any of InFoCAD’s graphic databases.

InFoIMAGE provides an Image Manager that enables users to manage large sets of primary images as well as manipulate and control the display of these images. Rectification, Height Filtering, Tiling, and Set files are some of the powerful features of the Image Manager.

The Image Manager can effectively manage up to 999 images at a time. InFoIMAGE provides two methods of ground control point rectification to calibrate these images to real worlds coordinates, Least Squares method and Direct Linear Transformation.

Once images are rectified, users can easily height filter the images (make them turn on and off automatically according to the zoom level), and/or tile the images, so that only images that intersect the view are displayed. These two features enable users to work efficiently with large sets of images of the same or different mean solutions.

Since images must retain a rectangular form, after the warping and stretching of rectification, images generally have distortion along their edges. This distortion is often a hindrance when working with overlapping images. InfoIMAGE provides an image crop command, which is used to create a seamless mosaic from several images.

Primary images are often used to perform on-screen digitizing, therefore InfoIMAGE provides two powerful commands, MAGNIFY and PIXEL SNAP for manual on-screen digitizing. These commands pop up windows, which magnify the area directly surrounding the cursor. This provides users with a clear view of the images for digitizing.

InfoIMAGE goes far beyond background images, on-screen digitizing, and vector overlay by providing a mechanism to associate images to database records.

 

These images are called Secondary Images and once associated to database records can be used in various ways:

• Images can be stored and retrieved from any of InFoCAD’s graphical database modules.
• Images can be used as graphic tags for the database records.
• Images can be retrieved and displayed in a wide variety of ormats, used in database views, and displayed through SQL.
• A hierarchical structure of images with the Image Schematic database model and the SCHEMA utility, which provides a graphical interface.

InfoIMAGE’s Picture Image Display Panel uses a point-and-click interface, which enables users to created sophisticated display formats for viewing database images or video without having to learn any complicated syntax.

In short, InfoIMAGE was built specifically for productivity and makes raster image display, raster-to-vector conversation, document retrieval, and graphical image management easy by providing user-friendly commands and utilities that almost do the work for the user.
