Beating Covid-19 impact

Personal and club funds may have taken a beating from Covid-19 avoidance measures. So here are two small but hopefully useful OCAD Aus/NZ initiatives in respect of OCAD pricing.

Firstly, 3 clubs in SA demonstrated a fast and effective way of taking advantage of discounts. They banded together as an informal ‘OCAD SA’ group and placed an order for 5 Orienteering Teams licences. Due to the process for managing Teams licences, each club is able to totally manage their allocation even though the licences are in the name of the group. The group ‘leader’ can place the order online in the Shop.

Secondly, for the remainder of 2020 or the end of the Covid-19 travel restrictions in AustraIia/NZ, I will continue to apply the 15% discount for 3 year terms. (The official discount reduced to 10% on 1st April). [correction to original post]

GPX file import changes

ADD Import, GPX: Assign symbols directly from <sym> node in Oribooklet gpx.

from March 2020 service update

The problem

This displays the symbol name assigned by the mobile orienteering app Oribooklet. Great idea but maybe not for the majority who get their GPX files by other means. The symbol name is obtained from the Symbol column in many GPX files. So non-Oribooklet users will generally find the POI number showing as usual but now alongside will be the word ‘POI’ or ‘waypoint’ or similar.

This has been reported as showing in a large text on import. In my test at right, it is shown in a very small text – prior to conversion to a text symbol, at approx. 3pt. Yet still very confusing.

Solutions?

So maybe this is a good time to suggest further improvements the GPX import.

  1. On import, only display symbol name/symbol if OriBooklet is identified in the GPX file header.
  2. or make it an option to display/or not, the Symbol column content.
  3. On import, provide an option to display any Comments column content – OruxMaps users may find this useful.
  4. Add to the existing import GPX selections, an option to select a text symbol to display such text.
  5. let me know of any further suggestions to put forward.

Download georeferenced satellite images

Did you know the OCAD acquisition of georeferenced satellite imaging is now quite easy? Neither did I until I stumbled across the OCAD wiki entry for Download georeferenced satellite images. And I was surprised at how easy it is and of a suprising quality.

Off course

Orienteering can heartfully say vale to Gary Starkweather, the inventor of the laser printer at Xerox. That invention was, and is, a lifeline for orienteering in small O populations as it;

  • reduces the cost of printing (early this century O maps were offset printed)
  • avoids the mark up of map changes – a source of error
  • avoids the mark up of courses – another common source of error

Gary continued development of the laser printer technology despite his Xerox boss telling him not to. Eventually it won a 3 way test of printer technologies at Xerox and came on the market in 1977, a huge success for Xerox.
