hslayers / hslayers-ng

User interface and map building extensions for OpenLayers

HSLayers-NG monorepo

This is a monorepo for developing HSLayers-NG Angular library.

Hslayers version	Angular version	Bootstrap	OpenLayers
1	1.7	4.5.3
2	1.7 + 9.1.x (hybrid)	>=4.4
3	9.x	4.x
4	10.x	4.x
5	11.x	4.x
6	12.x	4.x
7	12.x	5.x
8	13.x	5.x
9	13.x	5.x	^6.14.1
10	14.x	5.x	^6.14.1, ^7.0.0
11	15.x	5.x	7.x
12	16.x	5.3	7.x
13	17.x	5.3	^8.2
14	17.x	5.3	^9.0

It contains source code of libraries which need to be used in an existing Angular based container project:

• hslayers - core components and services for map application based on OpenLayers + Angular + Bootstrap,
• hslayers-cesium - Angular components for running HSLayers-NG UI with Cesium 3D map renderer,
• hslayers-sensors - Angular components for visualizing data from Senslog server using Vega charts.

Source code for ready to use application bundles which can be included in html files through <script> tags:

• hslayers-app - ready-to-use application built on HSLayers-NG,
• hslayers-cesium-app - ready-to-use application built on HSLayers-NG and Cesium.

Configuration for these applications can be provided through global hslayersNgConfig function which exposes an object containing a subset of most common OpenLayers classes through an ol parameter. In return the function must provide a JSON object conforming to HsConfig type. See example and config parameter descriptions.

• hslayers-server - a simple cors-anywhere based proxy server which can be used to overcome CORS restrictions, fill API keys for services such as Geonames used for search and other tasks. Copying and modifying the .env file to preserve secrets and not expose them for everyone and all kinds of requests will be necessary.

Integration

HSLayers-NG can be integrated into larger systems. See crx-hslayers for an actively maintained widget for Wagtail/CodeRed CMS. Check hub4everybody.com to see, what you can achieve with this integration.

Development

Development server

Run ng serve for a dev server which displays a simple hslayers based map portal with almost no map layers. Navigate to http://localhost:4200/. The app will automatically reload if you change any of the source files. It's based on hslayers-app project contained in this repository.

Build

Run ng build to build the HSLayers-NG library. The build artifacts will be stored in the dist/ directory. Use the --prod flag for a production build.

Running unit tests

Run ng test to execute the unit tests via Karma.

Running end-to-end tests

Run ng e2e to execute the end-to-end tests via Cypress.

hslayers-ng's Issues

Order folders in layer manager by name

To zoom to wms layer, If bounding box is not specified as attribute for layer, try getting it from GetCapabilities

mapove kompozice (nastaveni prav)

1. muzu otevrit cizi mapovou kompozici, pak ji ulozit znovu - a tim trivialnim zpusobem ziskam prava na tuto kompozici - pak ji muzu i smazat :))) myslim, ze tato mezera v pravach ma byt opravena

2. pokud pridam do verejne kompozici neverejnou vrstvu , a nasledne tu kompozici ulozim, tak ta neverejna vrstva se zobrazi komukoliv - protoze kompozice je verejna. myslim, ze se ma zomezit pridani neverejnych vrstev do verejnych kompozic

Clean up naming of all the components to include namespaces

Use names like this:
hs.layermanager.directive
hs.layermanager.controller
hs.layermanager.service
etc.

RDF selector for HSlayers NG composer

Like button and sharing on other social networks for Map compossition

It will be good to have like button for compossition, which will support sharing of permalink on Facebook. Aslo will be good to support sharing of permalinks for map compossition on other social networks (LinkedIn, TWitter, Google +}

When getfeatureinfo returns multiple html responses, all must be shown in the popup not just the last.

Rename map.js

map.js is not "extension" of ol.Map but object which contains Ol.map. Rename it to MapPortal or something like that

Generate layers in Layer switcher automaticaly from RDF files

Is there any possibilitties how to automatise generating layers in Layerswitcher automaticaly on the base of RDF files. Is some idea how to build for this some managment tool. And is there some possibilities how to conect atributes comming from RDF connect to Geometries.

Embedding into WordPress

Most of portals is now developed in Wordpress, will be possible to embed maps into Wordpress? it will be helpfull for potential exploitation. In past with old HSlayers Marek Splichal done some experiments

Problem with permalink

When i try load permalink first time (http://goo.gl/T03mDE), only screen with few buttons and cookie accept banner appear. After reload map is shown.
In console i got:

require.js?browserId=other&languageId=en_GB&b=6102&t=1467276235000:165 
Uncaught Error: Load timeout for modules: ol

Select objects from Virtuoso

Could be, that my idea is crazy, but what will be nice to be able similary like in catalogue select in Virtuso some type of objects. some class and this add to the composition. If we will store a lot of diferent types of objects in Virtuoso, this will be nice for building customised maps. And then use this objects like other type of layers. Do you think, that such apporach could be possible?

problem with KML layer

KML layer in the composition:

1. overrides the composition extend
2. messes the order of layers (goes to the bottom of the layer list)

See:
http://www.opentransportnet.eu/web/guest/create-maps?composition=http%3A%2F%2Fwww.opentransportnet.eu%2Fwwwlibs%2Fstatusmanager2%2Findex.php%3Frequest%3Dload%26id%3D6b8a02cf-a932-4e12-ac07-d6aacff35784

there the extent of the composition set to the center of Liberec and correct layer order is:

1. Open Transport Map
2. KML layer with bus stops
3. virtuozo layer with bus stops

WMS T is now working in compossitions

When you are preparing compossition with WMS T, in commpossition it works as normal WMS

Multi-dimensional feature attributes

The getfeatureinfo inspector should support complex xml structure like the features specified in this wfs 2.0 response http://services.cuzk.cz/wfs/inspire-cp-wfs.asp?service=WFS&TYPENAME=CP:CadastralParcel&request=GetFeature&version=2.0.0&SRSNAME=EPSG:3857&outputFormat=geojson&bbox=1701738.746692764,6439700.778020837,1703004.7349737375,6440197.618704691,urn:ogc:def:crs:EPSG:6.3:3857

Editing

Same module as for TreeLayer also provides functionality for editing

Example can be seen here
http://hsmap.cz/app/hsrs/index-debug.php

(Panel Editace)
First select layer (Vyberte Vrstvu) - for example Plochy k editovani 2
draw polygon
Hit odeslat.

(error will occur)

wms getfeatureinfo request

there are two issues:

1. if attribute is a url link - it gets copied infinite number of times
2. if there are lots of attributes not of them is possible to see

Saving to status manager - Failed

I visualized 3 datasets - type of point, line and polygon, changed its cartographioc representation and I wanted to save the map as a composition, which failed (see the enclosed figure for the description)

The data has around 1MB of the size.

Improved measuring

multiple objects
editing of already drawn objects

Check icons on the toolbox

Issue from Irene

Please. check the behaviour of the tool box in the map composer.

when i click on an icon, then it stucks over the second icon (see attached) and no matter which icon I choose, this stays there stuck just changing the icon in the middle.
Also, when making mouse over, the icons are changing their alignment and placing on the toolbox.

Also, I thought we have added some more transport icons after Prague meeting, but now seems a bit old here. Have we made any changes since then?

Many thanks.

Change to Layer switcher when compossition is open

Now the mas is in list of compossition. It is not very intuitive and understanable

synchronizace_posuvatka_casu_a_WMS-T_vrstvy

Pri posuvani casu dopredu a dozadu u WMS-T vrstvy dochazi k posunu zacatku casoveho intervalu (viz prilozeny obrazek, normalne zacatek intervalu je 03-04-2016 22:00 , avsak z obrazku je patrne, ze nejde vybrat zadnou hodinu pred 05-04-2016 21:00).

Map Compositions Count for OTN

COmming from Irene https://redmine.ccss.cz/issues/5959

As a usability feature, I would propose adding in the map component one extra textbox below the "compositions" tab (see attached) to show total number of compositions that would change following zooming in and zooming out (by map extent).

In the same sense, it would be very helpful to have an annotation of paging as we have in the listing of datasets (see attached no2).

Please check its feasibility and give me a timeframe as it is considered as an important usability feature.

Many thanks in advance for this consideration.

Problems with Embeded on SDI4Apps Blog

I don’t know, if it is generic error in Embedded or if it is problem with WordPress or only on SDI4Apps , but I have such problems with Embeding. Could be, that it is only question of configuration of SDI4Apps Web pages, but I am not able to check it.
So I am using next permalink http://goo.gl/T03mDE. I am generating iframe code

<iframe src="http://goo.gl/T03mDE" width="1000" height="700"></iframe>

And putting it into editor for blog. See

If I am switching to visual code it is OK

However when I am publishing it, it disappear. See

Opening permalink in Layer switcher

If you are opening HSlayers using permalink, maps is open with list of compossition. It will b better to open it with Layer switcher

Fix resource loading issues

Make loading sources from external domains possible by declaring global domain variable that will be used in URL assembly.

Permalink is not working correctly

If I am working with this Map composition on OTN portal http://goo.gl/T03mDE , the code is correct , if I am copping this code into other browser it works well. However if I am sharing it on Facebook of Google, there is not shared permalink, but whole composition. See attaached file

Possiblity to change order of layers

reading data from Virtuozo

after saving map composition there is a problem to read data from Virtuozo:
see this
http://www.opentransportnet.eu/web/guest/create-maps?composition=http%3A%2F%2Fwww.opentransportnet.eu%2Fwwwlibs%2Fstatusmanager2%2Findex.php%3Frequest%3Dload%26id%3D6b8a02cf-a932-4e12-ac07-d6aacff35784
or this

Status of map

Map should return to last state if you leave map and return back.

Proj4 issues

On fly loading of proj4js defs

Old version of proj4js provided on fly loading of non-available defs. New version doesn't allow this because proj4js/proj4js#165
this defs can be loaded for example from epsg.io

Proj4 defs names

I think that by proj4js is provided possibility to use names instead of EPSG codes. It will more user friendly

Publish description of JSON for description of compositions

We need publish description of Mapcompossition, (JSON) trough SDI4Apps, OTN and FOODIE. Please prepare this descrition, I can distribute this, we have start to push it as some way to standard. We need show this on SDI4Apps review

TreeLayer

Old HSLayers had class Layer.TreeLayer (http://redmine.ccss.cz/projects/hslayers/repository/entry/branches/hslayers-3.5/source/HSLayers/Layer/TreeLayer.js)

Init is done:
LAYERS.geoportal_base_kn = new HSLayers.Layer.TreeLayer("kn", "http://geoportal.kraj-lbc.cz/mapserv/hsmap/index.php", {project: "geoportal_base", transparent: true, layers: 'parc sprava'}, { title: "<b>Katastr nemovitostí a správní hranice</b>", visibility: true, ratio: 1, isBaseLayer: false, queryable: true });

Develop Wizard for selection from SPOI databaze

On OTN portal http://www.opentransportnet.eu/web/guest/create-maps Premek manualy prepared two filters into SPOI database alloving
SPOI - Car Service
SPOI - Transportation
We need prepare Wizard, which will alows to prepare such queries and store metadata for this queries

Identify behavior

At http://otn-dev.intrasoft-intl.com/explore-maps?hs_x=1606238.490305179&hs_y=6460289.967589872&hs_z=16&hs_panel=info&visible_layers=Base%20layer%3BAutomaty%3BCyklisticke%20trasy

When I click somewhere at the map where is no feature to identify, nothing happens. Expected behavior: Show Info panel with coordinates.
When I click on the feature, Info panel is shown with desired information. OK
When I click somewhere at the map again, the coordinates are redrawn, but information from last identified feature is still shown. It should be erased.

Multilinguality

Discussion: https://redmine.ccss.cz/issues/4732

Code "refractoring"

Go trough code and check if you are reusing functions as much as possible. For example code for loading of nonwms layers from ckan is writen at datasource_selector and also at ows_nonwms. So if you make change in one it will not be visible in another

Logical and Physical LayerList

Logical panel contains folders and is only some thematic order

physical panel describes order how the layers are drawn

Measure tool doesn't take into account the curvature of the earth (closer to poles the area is many times larger than expected)

OpenLayers 3 doesnt support geodesic measurement at this moment

Discussion: https://redmine.ccss.cz/issues/4721

Remembering status

If I am working on OTN Hub and I need login or I need registered myself I am losing my compossition. It will be good to remebmer this in status manager and then again open this on the same place. Probably it will be good generaly, when I am leaving and comming back

Don't closure hslayers_api
