Geocoder | The most featured Geocoder library written in PHP | Command Line Interface library

Yes, but you have to stop throwing away the data. MKRoute.Steps actually gives you all of the information you need, so first, set up RouteSteps to accept MKRoute.Steps:

So if I understand correctly:

1. User searches for an address
2. Map zooms to center around the chosen address
3. Now you want to know what is the screen X/Y coordinate of the chosen address

It's easy: it's exactly in the center of the viewport. So you can do just something like:

I'd also posted this question over in the Quasar Github discussions, and someone posted a brilliant solution.

I solved it. If you are using the react-native-intercom wrapper. You need to update it, after update everything works fine

First, be careful about the number of requests that you perform. The docs say:

• Send at most one geocoding request for any one user action.

• If the user performs multiple actions that involve geocoding the same location, reuse the results from the initial geocoding request instead of starting individual requests for each action.

• When you want to update the user’s current location automatically (such as when the user is moving), issue new geocoding requests only when the user has moved a significant distance and after a reasonable amount of time has passed. For example, in a typical situation, you should not send more than one geocoding request per minute.

And the old Location and Maps Programming Guide says:

The same CLGeocoder object can be used to initiate any number of geocoding requests but only one request at a time may be active for a given geocoder.

So, the whole idea of rapidly issuing a series of geolocation requests may be imprudent, and even if you were to do just a few, I would be inclined to avoid performing them concurrently. So, I would consider a simple for loop, e.g.:

shp2pgsql will by default create one table for each imported shapefile. However, you can have it load multiple shapefiles into the same table using the -a option.

The table spatial_ref_sys, as the name suggests, only keeps the data for the spatial reference systems, which are vital for operations like coordinates transformation.

The tables us_gaz, us_lex, and us_rules are related to the extension address_standardizer.

The other tables in the schema tiger are related to the extension postgis_tiger_geocoder - also system tables that shouldn't really worry about.

Precision of 6 decimal places gives you ~10 centimeter accuracy. Mapbox is using GeoJSON specification which has following recommendation about precision:

The size of a GeoJSON text in bytes is a major interoperability consideration, and precision of coordinate values has a large impact on the size of texts. A GeoJSON text containing many detailed Polygons can be inflated almost by a factor of two by increasing coordinate precision from 6 to 15 decimal places. For geographic coordinates with units of degrees, 6 decimal places (a default common in, e.g., sprintf) amounts to about 10 centimeters, a precision well within that of current GPS systems. Implementations should consider the cost of using a greater precision than necessary.

GPS-enabled smartphones are typically accurate to within a 4.9 m (16 ft.) radius under open sky. However, their accuracy worsens near buildings, bridges, and trees.ref

Here is a demo of distance accuracy when precision of 6 decimal places is used:

that simply means that the package you want to use is outdated and the flutter new update removed some functions that this package was using.

quick solution:

• outdate flutter by running this in the terminal 'flutter pub outdated' which I do not recommend
• or use an alternative for this package and make sure that this alternative is newly upgraded to be compatible with your flutter version

You're not having trouble with the lat or lon, what you're doing is passing in unnamed parameters to reverse_geo() that are not in the correct position. You should only pass in parameters positionally if you are certain they will be in the correct position.

You have:
