Android Mapping

There are plenty of GPS/Mapping apps for both Android and iOS but my favorite, so far, is Oruxmaps. This app seems to offer all the features I could want including:

  • Offline mapping from online sources
  • Offline mapping in vector format downloadable to the device
  • Offline mapping in Geo-Located PDF format which is useful for Motor Vehicle Use Maps as per the National Forest Service and available from staythetrail.org

Vector maps are available from OpenAndroMaps and are easily installed to the device by clicking the  button.

A good source of Digital Elevation Model (DEM) files is archive.org

Other options include BackCountry Navigator, All Trails, Avenza and Gaia and others. Neither of these apps offer as much flexibility as Oruxmaps however.

                $content = apply_filters( 'the_content', $content );

OpenWRT

Last week there was a need for a new feature on the main office router. This feature was not available. It seemed time to explore new options. The end result was an journey through the maze of the Open Source WiFi firmware world. The center of the maze turned out to be OpenWRT or LEDE.

Installation of OpenWRT went surprising well and configuration fairly easy. Options used included USB storage, sftp server and sqm (QoS). There will be a project page on this.
