Re: [Qgis-user] [QGIS-Developer] New QGIS Date/Time Tools Plugin

Nyall, What you mention has merit, but I was not kidding about trying to keep a plugin self contained for government use. To set up automatic downloading on our networks would require PKI authentication and that opens up another can of worms. I know how to deal with PKI because I already maintain

Re: [Qgis-user] [QGIS-Developer] New QGIS Date/Time Tools Plugin

Tim, I understand the position you are in and I really struggled in even wanting to put in the time to develop this plugin knowing that there would probably be a problem getting it accepted by the QGIS developers because of its size, but our users have a very real need for this capability which is

[Qgis-user] New QGIS Date/Time Tools Plugin

I would like to invite you to take a look at a new QGIS plugin that I have titled "Date/Time Tools". Currently it only has one capability to display date, time, and timezone information with conversions between UNIX time (Epoch), Julian dates, and ISO8601 date/time formats. It can calculate the dif

Re: [Qgis-user] z factor

I have a Lat Lon Tools plugin, Field Calculator function that generates the UTM zone. Nicolas, you just reminded me that you had suggested this to me earlier as a plugin. Something like that would be easy to add, but I'm not sure it fits within Lat Lon Tools which captures different coordinates, b

[Qgis-user] Vote for Lat Lon Tools Default Coordinate Order - YX or XY

It was suggested to me that the default coordinate order in the Lat Lon Tools plugin for coordinate capture and zoom-to tools should be "longitude, latitude" or "X, Y". Originally, Lat Lon Tools was designed to work with on-line maps which are generally "latitude, longitude" order. You can always

[Qgis-user] Adding Field Calculator Functions - Best Practices / Avoiding Name Conflicts

Greetings, Because of a user request I have been starting to expose Lat Lon Tools coordinate format conversion functions. I found out today that if you accidentally call one of your functions the same name as one of the existing functions, it causes QGIS to crash immediately. It got me thinking ab

[Qgis-user] Please show 15-20 plugin entries per page by default

I have raised this issue before, but I want to raise it again. Can we please have at least 15-20 plugins displayed by default on https://plugins.qgis.org/plugins/ and all of the other lists. This is what it used to be, but was changed fairly recently. Only showing 5 plugins is not very useful for b
