Serverless Raster or Imagery Tile Serving using PMTiles

-
A few months ago, I created a video tutorial about how to serve raster or imagery tiles using Github 
using TMS/XYZ Tile Serving protocol. The tiles can be consumed by a web gis app either as a base 
map or operational layer. Although the workflow is proven to be working for general cases, the tiles 
displaying and loading speed are quite mediocre compared to API-based serving such as WMS, 
WMTS, or ArcGIS Services. 

Now, there is one protocol called PMTiles that can also provide similar functionality with additional 
features and better loading/displaying performance. PMTiles in many ways is similar to Mapbox 
MBTiles format (the tiles are packed into a single file), or ArcGIS's TPK Package. However, PMTiles 
can be served directly using a common HTTP query (not like MBtiles or TPK which must be deployed into API Services to be able to be consumed by a webgis client). So, if you want to use Github as your host, you won't find an uploading problem because the file can be uploaded directly using GIT or Github Desktop. 

In this video, I will demonstrate how to write PMTiles from MBTiles (as far I know, there is no other 
way to write PMTiles other than this way), then how to deploy it using Leaflet JS (other Web mapping frameworks should also be able to call PMTiles as long as they support tile layer). 


maybe you are asking is there any other way to generate MBTiles from raster/imagery data??, The answer is yes, there are many software that can do it. Here are some of them. 

MapTiler - MapTiler is a popular tool for creating MBTiles from raster images. It is available both as a desktop application with a GUI and as a command-line tool. MapTiler can create MBTiles from a wide range of raster image formats, including GeoTIFF, JPEG, and PNG.

GDAL - GDAL (Geospatial Data Abstraction Library) is a powerful open-source software library that can be used to create MBTiles from raster images. GDAL provides command-line tools for converting raster images to MBTiles, such as gdal2tiles.py and gdal_translate.

TileMill - TileMill is an open-source map design studio that can be used to createMBTiles from raster images. It has a GUI that allows users to design maps using various data sources, including raster images. TileMill can also export maps to MBTiles.

QGIS - QGIS is a popular open-source GIS software that can be used to create MBTiles from raster images. QGIS provides a range of tools for working with raster data, including the ability to export maps to MBTiles.

Mapbox Studio - Mapbox Studio is a web-based tool for designing and publishing maps. It can be used to create MBTiles from raster images, as well as to design custom map styles and publish maps online.

Global Mapper

OpenMapTiles - OpenMapTiles is an open-source project that provides tools for generating vector and raster tiles from OpenStreetMap data. It includes a tool called "generate-tiles" that can create MBTiles from raster images.

Maperitive - Maperitive is a free and open-source desktop application for creating custom maps. It can be used to create MBTiles from raster images, as well as to generate vector tiles and export maps in various formats.

Kosmtik - Kosmtik is a free and open-source tool for designing and publishing maps. It can be used to create MBTiles from raster images, as well as to style and export maps in various formats.

TileStache - TileStache is a Python-based server software for creating map tiles from various data sources, including raster images. It can be used to generate MBTiles and serve them as a map tile server.


and many more.

 Seiring dengan semakin populernya penggunaan data spasial di berbagai institusi, baik pemerintah maupun swasta di Indonesia, banyak lembaga pemerintah telah mengembangkan Geoportal sebagai sarana berbagi pakai data geospasial resmi pemerintah. Berbagai macam peta dasar dan peta tematik dengan berbagai format telah dipublikasikan secara resmi oleh geoportal yang dikelola masing - masing instansi.  Berikut ini adalah daftar alamat web geoportal milik instansi pemerintah indonesia, baik kementerian, badan, lembaga, maupun pemerintah daerah yang telah dibangun dan diresmikan. Daftar ini akan diperbarui sewaktu - waktu apabila tercatat ada lembaga pemerintah yang telah membangun dan menerbitkan geoportal sebagai salah satu sarana berbagi pakai data dan informasi geospasial.  Kementerian / Lembaga / Pemerintah Daerah Pengelola Alamat URL Portal INA SDI ">https://tanahair.indonesia.go.id/portal-web/# Kementerian Kelautan dan Perikanan ">http://satupeta.kkp.go.id/ ...

HAE (Height Above Ellipsoid) and MSL (Mean Sea Level) Conversion Using Pathfinder Office

Di tepi pantai kok GPS-nya nilai ketinggiannya bukan nol ? mending bro yang saya alami malah nilai ketinggiannya negatif!, hmmmmm pasti GPSnya rusak, mari kita "lembiru" (lempar ganti baru)...... :) GNSS/GPS receiver secara default menggunakan acuan ketinggian (datum) berdasarkan ellipsoid WGS-84 (datum koordinat global), sehingga nilai ketinggian/elevasi yang diperoleh merupakan ketinggian diatas ellipsoid (HAE : Height Above Ellipsoid). Jika GPS yang kita gunakan menggunakan setting ini, maka tidak heran apabila ketika kita survei di pinggir pantai, ketinggiannya tidak nol atau malah mungkin negatif. Hal ini dikarenakan lokasi yang kita survei menurut WGS-84 ketinggiannya bukan nol. Ketinggian yang mendasarkan pada nilai nol diatas garis pantai rata rata disebut dengan MSL (Mean Sea Level). Kenapa bisa ada dua acuan ketinggian yang berbeda?. Hal ini dikarenakan bentuk bumi tidak sepenuhnya bulat, karena itu ketinggian nol di pantai ancol jakarta sejatinya tidak sama de...

TUTORIAL ORTHOREKTIFIKASI CITRA SATELIT RESOLUSI SEDANG (CITRA ASTER)

Orthorektifikasi adalah proses koreksi geometrik citra satelit atau foto udara untuk memperbaiki kesalahan geometrik citra yang bersumber dari pengaruh topografi, geometri sensor dan kesalahan lainnya. Hasil dari orthorektifikasi adalah citra tegak (planar) yang mempunyai skala seragam di seluruh bagian citra. Orthorektifikasi sangat penting untuk dilakukan apabila citra akan digunakan untuk memetakan dan mengekstrak informasi dimensi, seperti lokasi, jarak, panjang, luasan, dan volume. Citra tegak merupakan citra) yang telah dikoreksi segala kesalahan geometriknya, sebagai akibat dari mekanisme perekaman citra. Kesalahan geometrik citra dapat berasal dari sumber internal satelit dan sensor (sensor miring/off nadir) ataupun sumber eksternal, yang dalam hal ini adalah topografi permukaan bumi. Perekaman off nadir dan perbedaan ketinggian berbagai obyek di permukaan bumi menyebabkan adanya kesalahan citra yang disebut relief displacement. Relief displacement sendiri dapat didefinisi...
