Having problems after a trap.nz update

trap.nz often has updates, however, despite vigorous testing, sometimes there can be issues that are found after a release that is unexpected.

Here are the steps to take if you find that your trap.nz phone app is not showing as you expect it to.

1. Access the menu by the three lines at the top right of the screen.

How can I tell the difference between the types of rats I catch?

Three species of rats are present in New Zealand and all of them were introduced here.

Ship and Norway rats

The ship rat (Rattus rattus) is the most commonly found rat in New Zealand and is the smaller of the two European rat species. It has a tail that is longer than its body, and ears that cover the eyes when pressed forward.

Ship rats are widespread around New Zealand on the three main islands and on many offshore islands.  

The Norway rat (Rattus norvegicus) is different from the ship rat in that the tail, which is about 18 cm long, is thick and shorter than the body, which is about 20 cm long, and its ear doesn't reach the eye when pressed forward.

Norway rats are more typically associated with human activity and found in urban areas but they have also existed on more than 60 offshore islands.  

Kiore

Kiore is the Māori name for the Pacific or Polynesian rat (Rattus exulans). An adult kiore is approximately 4 cm shorter than an adult ship rat, but looks very similar and the two species are often confused. The tail of a kiore is shorter than the body.

How can I tell the gender of the rat I just caught?

rat facts 2.png

How do I tell if I caught a mouse or a juvenile rat?

 

A young rat will have a much larger head in proportion to the rest of its body.

Baby rats are born with short tails and these tails remain smaller than the overall length of their bodies; baby mice are born with long tails and they keep these long tails throughout their lives. Mice tails are at least as long as their bodies, if not often double the length.

It is important to note that rat tails are also much thicker than mice tails, though this may not be evident when a baby rat is firstborn. However, as these rodents age, you will soon be able to tell the difference between them based on their tails alone.

Understanding the difference between juvenile and mature possums

Understanding the difference between juvenile and mature possums

To avoid confusion when distinguishing between juvenile and mature possums, the key detail for juvenile possums is their weight, which is less than 800gm, which indicates the back rider/adult threshold.

The gestation period for a joey is 17 to 19 days. It crawls into the mother’s pouch, where it stays for five months before becoming a “back rider”. (A juvenile possum, often referred to as a backrider is any possum under 800gm.)

The joey is weaned at about 6 - 8 months, though some will stay with the mother until it is one year old. https://www.predatorfreedunedin.org/resources/possum-facts

Why can't new members see installations?

When a new member is added to a project without any permissions, they have limited access.

As a basic trapper they can:

A Project Administrator can update the new member's role to Advanced trapper to allow view only access to all installations via the website, or Manager complete access via the web and the app. If security and privacy is a concern, it is better to specifically assign installations to the trapper.

Read more about what the different roles mean and how to change members roles. 

Can I record one off kills on Trap.NZ?

In the event that a pest is killed by something other than a trap (e.g. roadkill, killed by cat/dog/firearm etc.), it can be useful to record this data as part of your project.

For instructions on how to add one off catches and observations click the link below.

How do I use the map tools?

Moving around the map

image-1631841475136.17.42.png

Understanding the toolbar 

There is a toolbar at the bottom of the map. You can see the name of each tool by hovering the mouse over the icon. The first map tool section will vary depending on what part of the website you are looking at.

map_controls_point.png Draw a point Visible for Traps, Bait Stations, Monitoring Stations, and Points of Interest
map_controls_line.png Draw a line Visible for Lines and Points of Interest
map_controls_polygon.png Draw a polygon Visible for Projects and Points of Interest. See "Drawing a polygon" below.
map_controls_edit.png Edit features Use to edit something already drawn on the map
map_controls_delete.png Delete features Use to delete everything already drawn on the map

Drawing a polygon

  1. To start drawing a shape on the map, click on the polygon tool to activate it (you will see the blue around the icon get slightly darker).
  2. With the polygon tool active, click on the corners of the area that you want to manage.  This will define the boundaries of your trapping project.  
  3. On the last corner, double-click to finish the drawing. The outline of the shape will complete and change to green.image-1631841292901.14.36.png

Editing the polygon shape

If you didn't get the shape quite right you can change it:

Starting over

If your drawing has gone wrong and you'd like to start over, you can do this at any time by clicking the "Delete features" tool.

Why don't the project stats on the main project map update immediately?

The project stats on the main project are are updated daily, not in realtime. If you have just added some data into your project, it won't show up in this stats box until the next day. If you want to check whether your records have saved, they will be saved in other areas of your project (e.g. to check if a trap record has saved, you can click on that trap, and a list of saved records will be visible at the bottom of the page).

The reason they are not updated in realtime is to improve site performance. As Trap.NZ has grown over the years, the site has become slower, and we found that updating this project stats box daily instead of in realtime improved site performance hugely.

Is my project data shared?

None of your project data is shared without your permission (please see our privacy policy). However we very much hope that you will give us permission to share summarised data from your project. Sharing summarised data from your project helps the national dataset grow and allows New Zealand to make more informed decisions about how we manage pests.

Each project has two privacy settings which are accessible by going to the My Projects page, selecting your project and then clicking "Edit":

  • List this project publicly 

    Ticking this lists your project in the Trap.NZ directory.  This allows others to find and request to join your project. The name, organisation, contact details, description, links, and location fields will be visible to the public. Personal details will remain private.

  • Share summary data

    Ticking this allows us to share summarised data from your project (e.g. the number of traps, catch counts, baits used, the approximate area managed etc). Information is aggregated at a 200m x 200m grid level.  This makes it difficult for anyone to determine the exact of traps and stations.

Detailed trap or station information such as names, notes, photos and "recorded by" fields are not shared. Likewise, profile information such as member names and addresses are not shared. These are private to your project.

How can I enter GPS coordinates for installation locations?

If you have GPS coordinates, you can enter them into the Manual Coordinates box when adding an installation. Then click the “Find using manual coordinates field” button to place the location on the map before saving the installation.

image-1634081324896.png

 

Note that the coordinates must be in decimal Lat, Long:
e.g. ​-41.545769706106, 172.15099409223

Or in NZTM format (New Zealand Transverse Mercator):
e.g. 1763693.1614139 5459118.2077669

If the coordinates are in another format or projection you will need to convert them first.

How to convert coordinates

LINZ have a handy converter here:
https://www.geodesy.linz.govt.nz/concord/index.cgi 7

For example - If your coordinates are in Degrees Decimal Minutes (DDM) e.g:
172 03.4 E 41 20.8 S

Then you will need to convert them to Decimal Degrees (DD) first:
https://www.geodesy.linz.govt.nz/concord/index.cgi?IS=WGS84_G1762&IH=-&PN=N&IC=M&IO=EN&ID=S&OS=WGS84_G1762&OH=-&OC=D&OO=NE&OD=H&YEAR=now&OP=4&CI=Y&do_entry=Enter+coordinates&ADVANCED=1

Pre- Authenticated Member

What is a pre-authenticated member?

 

This is a person who has created a trap.NZ account but has not verified their account.

 

To verify their account they will have to access the email address they provided when creating their account and find the email from trap.NZ, here you will find a  link you will need to verify your account.

 

If you can’t find your trap.NZ verification email. They are often in your spam folder.

 

The administration of a project will be unable to assign any installation to pre-authenticated member.

Why can’t I import data? it says I’m not using the correct file encoding.

If your CSV file is not being accepted and it says “Source file is not in UTF-8 encoding”, you may need to download it using another file code. In the case below ANSI needed to be substituted with Windows 1254 in the import page.

One off Android beta installs

Occasionally, we release app beta installations for instant access (bypassing the Play Store process.) The listings are available for a short time, therefore the following may have already expired:

 

v6.3.6 (QR / NFC)

 

By default, Android will prevent this until Internal app sharing is enabled. This can be done with the following instructions:

 

  1. Open Play Store.
  2. Navigate to Setting. (Click on the account profile picture. which is located at the top right corner of the screen)
  3. To Enable Developer Options. (Goto > About Section. and Tap seven times on the Play Store Version)
  4. Once you get the “You are now a developer!” prompt, you will see the “Internal App Sharing” option in the General | User Controls Section. 

 

App wont open - says “Login requires network coverage”

The app occasionally has an issue where it will not open and gives a message that it requires network coverage, even when you have reception.

This is a reply from an app user who found this worked for his Android phone

 

In our case this issue turned out to be about SSL certificates. The certificates installed on the Android device did not pick up the recent (2020?) changes to the root SSL certificate providers.

To test if you have the same problem as us, try the following:

Open a browser on your device and navigate to https://trap.nz
→ Trap NZ website should open OK
In the browser, navigate to https://api2.trap.nz
→ If you get an invalid SSL certificate error. Then you have the same problem as me.

SOLUTION:

On older versions of Android, the only way to update root certificates is via official Android software updates. You can generally do this by performing an ‘over the air’ Android software update from the Android settings menu, but in our case, we had to follow the manufacturer’s instructions (Zebra in our case) and manually load an updated Android OS image via a PC.
