TrigTools - Links Page

Places to find more information about Triangulation and Levelling

This page lists many of the varied sites I have come across in my persuit of information about trigpoints and maps in general, I hope they are useful! (They are not in any particular order, just as they come)

Map Websites
- This has moved to its own page here
- but couldn't forget to mention the Ordnance Survey, who have made all this possible
Groups and Websites about Triangulation
- TrigpointingUK.com or T:UK - site to log visits to trigpoints, also has a forum
- jeremyp.net - another similar site
- Trigonomy - active yahoo group discussing all things TrigPoint related
- OSBM - msn group where you can find pictures of many trigpoints and NPFBs
- Triangulation Pillar Waypoints - downloadable list of trigpoints - source of data for many sites above!
- my own TrigTools website ;-) (including Trigonomy Search)
Just what are Trigpoints anyway?
- couldn't do much better than T:UK - A brief explanation of trigpoints and Types
Levelling
- bench-marks.org.uk - database of OS benchmarks - particually FB's, with logging
  - This is still an early development site, but promises to be definitive source for BM details!
- My own Levelling section of TrigTools. Partically strong on the Second Geodetic Levelling
- OSBM - msn group where you can find pictures of many Flush Brackets used during Levelling activities.
- Fayers - site listing locations of most of the Fundermental Benchmarks. Also used to compile the FBMlist.
What type of BenchMarks/Flush Brackets are there?
- See a list I've compiled on my Levelling FAQ page
GPS - Global Positioning System
- National GPS Network - all about using GPS in the UK
- gpsinformation.net - if you are thinking of getting a GPS receiver and/or software then theres probably a review here
Just what are Passive Stations?
- They are the markers used GPS positioning, many are reused Triangulation Pillars and Fundermental Benchmarks, see here.
GeoCaching - a sport loosly tied to Trigpointing
- Geocaching Portal - lots of useful links
- Geocaching.com - all about well geocaching
- GeocacheUK.com or G:UK - geocaching targeted to the UK cacher

DISCLAIMER: I developed this tools for my own use, so they don't look that pretty. I hope they work fine, but there may well be bugs. Please email me if you find any... All the programs are hand developed, but the data used is borrowed from other locations, namely the Trigonomy Yahoo Group and trigpointinguk.com, thanks to them for making the data available.
