I've put this data set into 1st - three columns, the first being the
names, the next Longitude and the last Latitude.  I plotted Latitude (Y)
against Longitude (X) using Name as the labelling variable.  What 1st
does is to generate a plot and provide a table with a list of the Names
together with their plotting symbols, as a !Drawfile or a sprite.

To write all the names on the plot itself would become more than
somewhat confusing, I'd guess.  So would any sort of labelling facility
with more than a few dozen points!

If you'd like to see the "plot" please email me!

I may be able to help, although my application takes OS references, then
plots them in various ways on a DRAW map of the UK. At the mo it draws a
cross or a triangle or a circle or whatever, of different colours, or can
draw complex lines, for example to plot a motorway.

Adding captions shouldn't be too difficult (he said, it's never like
that), and I'd be glad to have a look, but I'm just going out the door for
a week, so email me at the address below if you can make sense of it.

Somewhere I'm sure I have a routine to convert from Long/Lat to NG.

However the accuracy of my app may not be anough - those lat/longs you
have are very precise, whereas my app only takes NG refs like 'NT2677' for
Edinburgh.

Not directly, but you can use google maps to mark your own locations.
We've started one so that club members can show what area they live in.
The only complaint is that you can zoom in and find peoples exact location,
so we recommend they just use the nearest major feature if they are worried
about privacy - the site its on is password protected, but even trusting
google isn't that wise. Here is an early screen shot:-

A DRAW map of the UK would be useful - where do you find such things
please?  Are motorways, canals and railways on separate layers?

Barry

Adding captions is not straightforward - if you add them above and to
the right of their location, then they can overlap. Have included a
BASIC routine to produce a DRAW file, converting from Lat Long
to Grid references (approximation accurate to AB123456, i.e. 100m)
putting place names onto a Grid.
Use the following BASIC programme to create a drawfile showing
the places on a grid:
http://www.svrsig.org/DrawTown.zip
after first loading the utility 'MakeDraw'
http://www.svrsig.org/software/MakeDraw.htm

Why not use the exact formula for converting lat/long to national grid
(which may be found here:
http://www.posc.org/Epicentre.2_2/DataModel/ExampleofUsage/eu_cs34h.html

) - well it's too complicated and the formula I use is good enough
to plot GW signal boxes on a graph (see
http://www.svrsig.org/GWMap.htm ) created by a simple PERL file.

Hope this helps.

 
 
 

1. Bluez on familiar arm-linux (ipaq 3870), cannot get class name and device name

Hi all, I have a few questions about the installation of bluez on ipaq
3870 (familiar linux). I have installed the protocol stack on the
familiar linux and the blue light of the 3870 is flashing (so it SEEMS
alright).

hci0:   Type: UART
        BD hci_sock_release: sock c2e5ce80 sk c3051420
        Address: 00:02:C7:08:69:D8 ACL MTU: 128:8  SCO MTU: 64:8
        UP RUNNING PSCAN ISCAN
        RX bytes:202 acl:0 sco:0 events:7 errors:0
        TX bytes:42 acl:0 sco:0 commands:9 errors:0

However I cannot get the device name and the class name of the HCI by
issueing the following command

h4_recv: n_hci c037d800 count 8 rx_state 4 rx_count 213
h4_recv: n_hci c037d800 count 17 rx_state 4 rx_count 205
h4_recv: n_hci c037d800 count 17 rx_state 4 rx_count 188
h4_recv: n_hci c037d800 count 18 rx_state 4 rx_count 171
h4_recv: n_hci c037d800 count 17 rx_state 4 rx_count 153
h4_recv: n_hci c037d800 count 13 rx_state 4 rx_count 136
hci_sock_setsockopt: sk c3051420, opt 2
Can't read local name on hci_sock_release: sock c2e5ce80 sk c30517c0
hci0. Conhci_sock_release: sock c2ea32a0 sk c3051420

It is similar if I want to get the class name. If I use other IPAQ
(PocketPC) to search this device, I found the device name and type
name are "iPAQ PocketPC" and "Unclassified Device" respectively. The
l2ping command also doesn't work.

l2cap_sock_create: sock c2fd5d00

DO I set the bluetooth stack wrong? Thanks for any suggestion..
