My scenario is that I will want to create and load several vector basemap files into the same map. I have an ArcGIS Runtime mapping application with both basemap layers and operational layers, and there are points, lines, and polygons among both the basemap and operational layers. Cartographically, I need points on top of lines on top of polygons, so I need to mix my basemap and operational layers. The top to bottom Z order in other words needs to be ...
If I want to use vector basemaps then that makes 3 basemap .vtpk files I'll package into an mmpk. The catch is that ArcGIS Pro is forcing a white background layer for my vector basemaps, and the transparency symbol option doesn't seem to be available for the background layer in the p12\resources\styles\root.json file. That white background is blocking everything below my basemap point layer.
The first step is to click the select style button which will take you to the style configuration page. In this exercise I will be focusing on the city of Istanbul. The aimed result is to create couple of nice looking maps that I can use as wallpapers designed to fit the display settings of different devices.
I want to make a vector seamless tiel for use within inkscape to apply to objects. I have no probs making seamless tiles to export as bitmaps or pngs and they work good in GIMP, but when I follow the guide for making seamless vector tiles, a la: I get seams showing between the tiles. I am also using a coloured bg which might be part of the problem since the examples in the link above are done with a white bg (same colour as the seams).
But funny thing is I have some seamless patterns I made about a year ago available to me in inkscape, transparent background, but then can be applied to a transparent object and laid on top of the object to which I want to apply the pattern. But for the life of me I can't remember how I did it. This would actually be the best, most versatile solution if anyone has a link to another tut shouwing how to make such patterns and save them in inkscape for use with inkscape I would appreciate reading it.
It seems odd that there are not more sites with similar solutions out there since this bug in inkscape appears to go back 11, yeap that's right, 11 years!!! Sheesh. I know this is opensource and free, but come on, tiled patterns are a fairly common requirement, and 11 years to ignore a bug like this seems a little over the top. I guess many people who can't afford AI settle for rastered tiled patterns, but there is no need.
on the node you wish to clone (e.g. a group). The first four values don't seem to matter (but they are required, even if they are zero), but you want to set the width and height (e.g. 64x64). It appears these values are used by the clone tool when you set the "use saved size and position of the tile" checkbox.
Hello. I am using the Vector Tile Style Editor (beta). I have updated my colors, set background to hillshade, and set the "Land" transparency to 80%. It looks great in the editor and I hit save. Now when I open the tile layer in a new web map, the hillshade is gone. I can add another layer, like "World Hillshade", but it's a separate layer and looks poor when zooming in/out. Have I missed something that doesn't allow me to save the transparency to keep the hillshade visible? Thanks.
When saving a custom vector tile layer (i.e. style) from the Vector Tile Style Editor app, it only saves the vector tile layer. A tile layer can only be vector (your style) OR raster (hillshade), not both. The Editor does not save out as a Web Map. The background hillshade and imagery available to view in the Editor are as background images, for reference only. You will need to compile a web map from the layer(s) you wish to display. This is the hillshade that's available as a background layer in the Editor and can be added to your web map to go with your custom style that has the transparency applied. Add both layers, move them to the base layer and order them accordingly.
To your other point of less than ideal performance having the vector map and raster relief... there is a known issue with the latency of the display when panning and zooming. Alternatives to improve this appearance are in work.
Vector tiles do not contain the original feature geometry. Mapbox GL does provide an api that delivers GeoJSON, but it isn't going to be your raw data: if it was, then the map would be slow and inefficient, since raw data is over-detailed.
It would be great to make patterns/tiles with vectors.
At least, being able to use a SVG as an image (in Tile mode). Uploading it or even copy/pasting it - since Figma is able to copy/paste SVG code.
In this release, the Light, Dark, and Normal map styles were redesigned by our cartographers from the ground up, although the design principle remains the same: these map styles are optimized so that your data is the hero of the map visualization. Notice how, in the example below, as I toggle map styles, the map style smoothly fades between colors. A benefit of the vector tile technology is that the colors in the map style are simply redrawn locally on the machine. This means that, when swapping between Light, Normal, and Dark, you can expect to see reduced network traffic.
With vector tile maps, new background map styles, and new contextual map layers, the out-of-the-box mapping capabilities of Tableau have gotten faster, more expressive, and more delightful. Exploring your location data is fast and fluid, and you can even integrate your own custom vector tile maps from third-party providers. Intended to augment your exploration of location data, these maps are built into the Tableau platform so you get the integrated experience you already know and love.
Just as applications make assumptions about what information exists in a database, so do Mapbox tools make assumptions about how vector tiles store geographic information. Understanding these standards can help you understand how to work with Mapbox vector tiles.
This guide covers file format, examples of geometry encoding and attribute encoding, an explanation of the importance of winding order, and a list of concepts not included in the Mapbox vector tile specification.
Vector tiles are encoded as Google Protobufs (PBF), which allow for serializing structured data. For clarity, Mapbox Vector Tiles use the .mvt file suffix. The specification details are largely structured around the rules implemented in the base .proto file.
To encode geographic information into a vector tile a tool must convert geographic coordinates, such as latitude and longitude, into vector tile grid coordinates. Vector tiles hold no concept of geographic information. They encode points, lines, and polygons as x/y pairs relative to the top left of the grid in a right-down manner.
Attributes are encoded in a series of tags that exist within a feature in the vector that have integer values that reference keys and values designating the original key:value pairs from the geometry. For large geometry, this removes redundancy for attributes that have the same keys and similar values.
Winding order refers to the direction the vector tile draws a ring, either clockwise or counter-clockwise. Many geometries are multipolygons with "holes," which are also represented as polygon rings. It is important to be able to infer winding order to extract source data from a vector tile and understand if the geometry is part of a multipolygon or a unique polygon.
Extracting the original data from images has been difficult on maps in the past, because of the loss of underlying metadata from the geometry that might have been used to create the image. Yet, with the introduction of client side rendering of vector tiles via GL technologies, the raw geometry data has become useful for a source of information outside of rendering.
This specification IS NOT intended to explain how to use vector tiles as a dataset. This is something that has been considered for the future, but it will likely be a separate specification. This specification does not cover how to store, request, or share vector tiles. Consider this specification like how the PNG spec explains how to pack data.
The specification does not explain how geographic data should be clipped between vector tiles since clipping, like simplification, can be executed in many ways. Mapbox specifically clips features at a buffer around the tile (see the encoding example above). Any geometry within this buffer is assumed to carry over to another tile. This is up for consideration for a future release.
A common question, when it comes to clipping is "how do renderers know which lines to connect for clipped geometry?". This is the reason Mapbox adds a buffer to vector tiles and clipped geometry. When it is time to render, Mapbox sets the canvas to the exact tile size, which sets the edges outside of the visual frame, thus the tiles all line up. So, there is no need to know which nodes are part of others for rendering purposes. Although, you could use the id field in the protobuf to store information necessary for reconstructing polygons.
