Review

Loads images directly from the Internet using the ECWP protocol if needed and performs a progressive scan and load over very large images. Offers the possibility to load multiple maps and arrange them on separate windows, thus you can load images with formats like ERS or DAT.

ER Viewer is a simple utility that allows to open and view raster GIS images, like ERS, ALG, DAT and many more, becoming a trustworthy tool when working with the most popular formats.
The key feature of this program is the ability to easily navigate through very large images performing a progressive scan and load, thus enhancing the overall speed and reliability. You can load multiple maps and arrange them on separate windows (it's an MDI application) and browsing them without losing performance significantly.
Moreover, ER Viewer is capable to load images directly from the Internet using the ECWP protocol (ecwp://). Thus, if you know any valid data source you can easily connect to it and retrieve the file.
Once you have the image over the screen, there is just one tool available: a ruler to measure distances. What to say...it just works :)
Of course, as an image viewer (primarily), you can't expect a lot of features from such application. Despite of this, the very few options available are enough to effectively take advantage of this program.
