Aussie/Kiwi of Eureka Orienteers & keen mountain bike trail rider. OCAD user since 1996. Produced trail maps since 2005 for Cyclic Navigator events. In 'retirement' am providing services based on my interests and I particularly enjoy helping the OCAD cartography user community.
Recently i imported a Shape file and added spot height symbols to a trail map. Then I selected Database > Add text from database records in order to place the actual heights adjacent to the symbols. However every height was identical.
Eventually I consulted OCAD Inc support and I discovered that selection of a unique key when importing sashape file is very important. Usually the key presented to me in VicMap shape files is PFI or UFI so i hardly look at it. However this time a different key showed and I simply accepted it.
However it turns out that for some operations, the key field must have unique entries in the shape file. In this case, to deliver the text that matched each spot height instance.
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
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.
So maybe this is a good time to suggest further improvements the GPX import.
On import, only display symbol name/symbol if OriBooklet is identified in the GPX file header.
or make it an option to display/or not, the Symbol column content.
On import, provide an option to display any Comments column content – OruxMaps users may find this useful.
Add to the existing import GPX selections, an option to select a text symbol to display such text.
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.
Read my knOCAD post for further explanation of some of the OCAD wiki instructions.
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.
Export PDF: Support Geospatial PDF (WGS84) for georeferenced OCAD maps. Note, as yet these are not suitable for Avenza publication so continue to use world TIFFs.
Load symbols & colours, option ‘Add’: Uses added colour’s number if the number doesn’t exist in target colour table.
plus improvements to Legibility checks, Symbol sets, ISM conversions.
more to come including sketch layer for mobile.
1 year or 3 year subscription?
If you are teetering on the choice then here is a heads up. On 1st April 2020, the discount for 3 year subscription will reduce from 15% to 10%. ocad.com.au/shop.
OCAD subscription users
OCAD recently published a reminder re the availability of a temporary backup of your session. That setting is in Options>Preferences>File.
While you are there, select Help and check out the other useful options. Then take a look at Options > Back up and Restore Options. This allows you to save your Preferences and Shortcuts – very useful if you need to reinstall your OCAD or move to a new PC.
Do read the change list when updating
You load OCAD to work on a map and perhaps take an offered update right then. I suggest you don’t decide to read the list later. You are likely to forget and may overlook something important such as this change in the March update;
CHANGE Symbol Sets, Orienteering: Order of colors for ISOM 2017-2 and ISSprOM 2019 symbol sets improved.
Don’t get caught out.

Has the move to ISOM being expressed in CMYK rather than Pantone, been successful? Not entirely.
Some users are finding colours such as blue (lighter) and purple (magenta) to be inadequate in some situations. This is more likely to be true of MTBO where we are unable to bring the map closer to our eyes.
Provided you aren’t creating maps for an international event, you could consider the Swiss Frey colour palette. This is an update of a palette brought out 3 or 4 years ago to provide a more accurate colour rendition for digital print. The first palette was developed on a Xerox Versant, the latest on a current model production level Konica Minolta. Another colour of relevance to MTBO is line brown for contours. The Frey swatch has a dark brown which is very close to the brown Jim Russell and I developed for MTBO digital print some years ago.
The palette has colour numbers consistent with the ISOM 20187-2 palette. Thus using Map > Colours > Select colour swatch > Load colour swatch > ISOM 2017 Color Swatch Frey Digital Print makes it easy to change your ISOM palette to the Frey palette in whole or by moving specific colours. View an English translation of the German.
ISMTBO blues are close to the Frey blues. However you might like to use the Frey brown for lines (15 Braun 100% – Linienobjekt’ 30,70,100,0) to provide more legible contours. If using Load colour swatch to make the change, ensure you untick the 3 options at lower left of the swatches.
You might like to first print, on your intended digital press, this sample pdf of the Frey palette. The German/French sub-titles at left on the pdf translate as ‘Print Resolution’.
Thank Gladys West for your GPS capability
In A Mathematician Idolised, Cosmos magazine gave a brief account of Gladys West’s significant contribution to the Global Positioning System (GPS) that mappers are increasingly using. Gladys was a key developer of the first highly accurate geodetic earth model (geoid), that was the basis of the GPS.
If you watched the film or read the book Hidden Figures, Gladys West is a contemporary of those women. While they worked for NASA, she worked for the US Naval Weapons Laboratory. However, she was equally embraced by Air Force Space Command with her induction into the Air Force Space and Missile Pioneers Hall of Fame.
The introduction sets the scene for current mapping. Note that references to OCAD 2018 also apply to OCAD 2019 which under the continued update model is the same product. In the 2020 subscription period, the product will drop the year suffix.
Gathering the data
Here Barry covers data sources and gathering. Some of these are NSW specific but other state equivalents should be readily identifiable by your club’s seasoned mappers. Lidar input is covered as is Kartapullautin.
Creating a base map in OCAD 2018+
Here we have the four key steps. These are followed by a note re use of Kartapullautin to better determine runnability.
Alternative mapping tools
This section covers Open Orienteering Mapper (OOM), OL Laser, LAS Tools and some useful links. Barry does say that if you use current OCAD, you wont need this information. It is great that he has catered for these other orienteering mappers.
This POC is unusual downunder in that users have the choice of participating by way of MOBO mobile app
or traditional paper map. MOBO utilises QR codes on posts and was
selected because it also provides the opportunity for another QR code on
the post to showcase nearby natural or historic mining features in the
Wesley College, Clunes Campus used the POC 3 times recently (traditional maps) and were delighted with the outcomes for their students. Next year they are looking at a more challenging course for selected students and this will likely be provided via MapRun which doesn’t require fixtures at control sites.
OCAD 11 & 12 users, help on ISSprOM2019 is a click away
Helpful ISSprOM2019 update documents and crt files have been prepared by Michael Wood with the help of other kiwi mappers. These include symbol sets for OCAD 11 which can also be used for OCAD 12.
The Orienteering NZ Mapping Bulletin dealing with ISSprOM2019 comes in two versions – one for clubs and the other for experienced mappers. Disseminating the sometimes complex ISM information in this way is a great idea as it enables non-mapper club experts to more easily get to grips with the issues and thus make better decisions on club mapping.
OCAD 11 & 12 users can get a symbol template for the new ISSprOM2019 standard. The file is for OCAD 11 but is readily usable by OCAD 12. OCAD current version users get that file during updates or via the means outlined in our recent Springtime 2019 Downunder eNews.
And there is even a pdf of the ISSprOM2019 legend (at right) especially for field work. Plus some other tools that OCAD 11 users might welcome.
