Go to the desired location in the map, set two markers by clicking the map to define a rectangle (or enter coordinates manually). Click the button [get data]. Optionally you can change the number of elevation samples you want in each direction, the more the better (max 400). You can also change the number of contours or set custom contour values. You can save some data in cookies, however there is a limit. Use the manual saving text areas below alternatively.
This service comes without any warranty whatsoever, including but not limited to functioning or correctness.
Resources: This service uses ArcGIS Map by Esri, the OpenStreetMap, Geocoding by Nominatim, Mapzen, Leaflet, jQuery and the CONREC contouring algorithm by Paul Bourke and Jason Davies.
Created by Christoph Hofstetter (christophhofstetter (at) gmail.com) 2013-2025If you want to have the contour maps as an individual layer (e.g. to create overlays) you can copy the code underneath the image below and save it as an svg file. Please note, as for now, the drawing below is square and you may want to stretch it to cover the actual area in a map.

: These servers were designed to convert analog video signals into digital streams for network monitoring. Modern Axis cameras typically use more secure, updated firmware and protocols (like ) and are often managed via AXIS Camera Station Risk Mitigation
Configuration
: Restrict access to the server's IP address to specific, authorized MAC addresses or IP ranges. 5. Ethical and Legal Note
If you are managing one of these devices, it is highly recommended to: Update the firmware to the latest version available on the Axis Support Site Change default passwords immediately upon installation. Disable public access
The 1l (one-L) might cause a logging error or odd behavior in the HTTP parser. While no high-profile CVE ties directly to “adds 1l”, it could be a leftover from:
An Axis video server (like the legacy 240Q or 241S series) converts analog video signals into digital streams. This allows older analog CCTV cameras to be managed over an IP network. The indexframe.shtml file is a core component of the web-based viewer for these devices. The Security Risk
The exposure of these servers via a simple Google search presents significant risks:
