Complete microwave link feasibility planning online with Gmaps and SRTM3 height data

You no longer need to buy an expensive Microwave Link Planning Tool to check the feasibility of microwave links, can now check the feasibility from scratch and online by using my Google Maps Microwave Link Feasibility Tool. First go to the line of sight tool at http://members.chello.at/stephen.joung/indexDistanceElevation.html
where you can enter the Site-A and Site-B by entering addresses, coordinates or simply by clicking on the map. You can zoom in and out with the mouse wheel or by using the controls top left. A new feature is that the site will remember you (if you enable cookies) and the next time you visit the maps will be set to the area and zoom level that you were last at. You can switch between maps, satellite and terrain views witht the control top right. After you have selected the A and B sites the tool will calculate the coordinates, bearing, distance etc. and also gather the height data for the link which it displays as a path profile. You can click on the path profile to display it in a separate window and print it out. You can raise the antenna heights until you achieve line of sight. When you are satisfied with a link you can click on the export button and the link is exported to the link engineering tool, where you can set the antenna sizes, frequency band, transmit power etc until you achieve the required availability. You can then print out a link budget for the link.

Google maps weather report

I have now included a weather report in my Google maps applications, you can find it here. It is very simple to use, simply click on the map or enter the address of where you want the weather report for and the temperature, humidity, wind speed and cloud conditions from the nearest International Civil Aviation Organization weather station are displayed on the right of the map.

As usual with my maps you can zoom in and out with your mousewheel or with the control on the top left. Click and hold the left mouse button to drag the map.

Enjoy it and any comments/suggestions are welcome.

Google Maps pedometer with height profile

I have now included height data with my pedometer so you can see the path profile of your run and know how high you have climbed. You can reach the pedometer here

Zoom in and out with your mousewheel or with the control on the top left. Click and hold the left mouse button to drag the map. Click the left mouse button to set the markers. Click on “Remove last leg” to delete the last leg entered and continue.
