 Hi,

 Json datatypes http://www.tutorialspoint.com/json/json_data_types.htm do 
 not map perfectly with OJ datatypes. Strings can be separated from 
 numbers, though, but there is another problem in missing schema. Each 
 feature can have different attributes.

 I believe that GDAL is scanning the GeoJSON file twice for finding all the 
 attributes which appear in the data and analyzing their datatypes. Rather 
 often GeoJSON is converted from GIS data and then schema is fixed so that 
 all features have same set of attributes and empty ones are marked as 
 NULL. Still it is hard to know the type of attribute if it is NULL.

 Code for reading GeoJSON with GeoTools is at
 https://github.com/geotools/geotools/tree/master/modules/unsupported/g
 eojson

 An easy start could be to read the first one feature and build schema
 with attribute types double, string, boolean. But what to do if there
 are null values? Read first hundred? Read until first not null? Or let
 user make a header line with schema into a separate file
 "basename.jsont" like with the GDAL CSV driver
 http://www.gdal.org/drv_csv.html

 attr_1:string;attr_2:integer;attr_3:double

 Sorry that I can't give simple answers, I thought it would be easier and 
 handled by JTS already.

Hi all,

The current behaviour for Feature Info panel is different from

It is not possible to just flash the selected row, as the
corresponding feature is selected.

Furthermore, when a feature is selected in the map (because its
row was clicked on FeatureInfo), then it appears in subsequent
Info panel, even if the feature is not part of the info selection
set. It is a source of confusion when checking features.

Is it possible (or where can it be done) to add an option to keep
old mechanism: clicking on a row flashes the feature, clicking on
the select button selects the feature on the map ?

Thanks

Nicolas

[JPP-Devel] Feature Info panel and feature selection

2016-07-01 Thread Nicolas Ribot

Hi all,

The current behaviour for Feature Info panel is different from previous
versions:
Now, when a Feature Info row is clicked, the corresponding feature is
automatically selected.
It is not possible to just flash the selected row, as the corresponding
feature is selected.

Furthermore, when a feature is selected in the map (because its row was
clicked on FeatureInfo), then it appears in subsequent Info panel, even if
the feature is not part of the info selection set. It is a source of
confusion when checking features.

Is it possible (or where can it be done) to add an option to keep old
mechanism: clicking on a row flashes the feature, clicking on the select
button selects the feature on the map ?

Thanks

Nicolas
