depthmapX is an open-source and multi-platform spatial analysis software for spatial networks of different scales. The software was originally developed by Alasdair Turner from the Space Syntax group as Depthmap, now open-source and available as depthmapX.
How it works

depthmapX works at a variety of scales from buildings and small urban areas to whole cities or states. At each scale, the aim of the software is to produce a map of spatial elements and connect them via relationship (for example, intervisibility, intersection or adjacency) and then performs a graph analysis of the resulting network. The objective of the analysis is to derive variables which may have social or experiential significance.

Visual analysis

At the building or small urban scale, depthmapX can be used to assess the visual accessibility of a place in a number of ways. It can produce point isovists, (polygons that represent the visually accessible area from a location) and isovist paths that show how the view changes when moving through a space.

Isovists are the core element behind Visibility Graph Analysis (VGA), acting as the joining mechanism that converts a dense grid to a graph of intervisible points (a visibility graph), which may then be analysed using various graph measures. depthmapX provides local measures of visibility such as the isovist area and perimeter but also global ones quantifying building traversal and space centrality.

VGA can also be used as the core of an agent-based analysis. In this type of analysis, a number of software agents representing pedestrians are released into the environment. Each software agent is able to access the visual accessibility information for its current location from the visibility graph, which informs its choice of next destination.

Agent analysis

depthmapX allows for simulating different types of pedestrian behaviour by providing various ways for an agent to choose where to walk, such as towards larger spaces, long lines of sight or parts of their view that are occluded. The paths of the agents and their numbers passing through gates can be counted, and compared to actual behaviour of pedestrians passing through gates.

Axial and segment analysis

At the small to medium urban scale, depthmapX can be used to derive an axial map of a layout. This means it can derive a reduced straight-line network of the open space in an environment. The axial map has been the key analysis method of space syntax research for many years, but the mathematical derivation of it is novel.

The automatic derivation within depthmapX allows an objective map for researching spatial form and function. Once the map has been generated, it may be analysed using graph measures, and the measures may be transferred to gate layers in order to compare with indicators of pedestrian or social behaviour. For larger systems where the derivation algorithm becomes cumbersome, pre-drawn axial maps or downloaded maps (such as road-centre lines) may be imported.

Axial maps can also be converted to segment maps by breaking down long axial lines into a sequence of segments that lead from junction to junction. These may be analysed using a variety of techniques that accumulate depth, such as the degree of angle change from one segment to another, metric distance, or segment steps. Examples include the calculation of the number of shortest angular paths through a segment, or the average metric distance from each segment to all others.

depthmapX can import pure geometrical data such as floor plans or line-centre maps. which may then be converted into spatial networks. They can also be converted directly into existing networks such as VGA, axial maps and segment maps. The software provides an interface for exploring and modifying these networks by representing them as geometries but also by displaying the various parameters associated with them. Finally, it allows for limited extensibility and combination of the various measures by providing a simple scripting language called "salascript".

New developments

Recent development efforts have resulted in an alternative 'command-line' interface that allows for automating the preparation and analysis of spatial networks with minimal user interaction. With this new interface the analysis of multiple different projects can be carried out unattended and without the need to have the graphical user interface open.

In this form depthmapX may also be embedded in projects using other programming languages such as R and python, allowing them to harness the various types of analysis in more complex applications.

TELUK INTAN, May 5 - The federal government has allocated RM82.5 million for development projects and infrastructure upgrading works around Teluk Intan, said Local Government Development Minister Nga Kor Ming.

Nga said that the allocation included a six-kilometre flood mitigation project along Sungai Perak, which is scheduled to begin this year and to be fully completed in 2026.

"I expect once the flood mitigation project is completed, the flood issues in the area can be fully addressed," he told reporters after a working visit at Pasar Besar Teluk Intan here today.

Nga said for the upgrading works, a total of RM600,000 was allocated to repair roofs and provide special parking lots for persons with disabilities at the Medan Selera Glutton Square in Jalan Ah Cheong.

It also involves upgrading facilities at the hawker centre in Jalan Maharani, such as installing a new floor and heat shields, while another RM800,000 is for upgrading Pasar Besar Teluk Intan, such as electrical wiring and digital signage installation.

"Upgrading works such as improving landscape features, installing solar lights and improving facilities for the disabled will be carried out at Teluk Intan Riverfront recreational park, with an allocation of RM500,000," he added.

Nga said the allocation was aimed at increasing the level of cleanliness, safety and comfort of traders, as well as visitors, to boost the local economy. - Bernama

Teluk Intan is Perak's third largest town. From its name (translated as "Diamond Bay" in English), one may think that it is, in fact, a bay. But actually, the town was founded around a meander of the Perak River and only looks like it's near a bay.

People familiar with Teluk Intan - previously called Teluk Anson - will also know the Menara Condong, an old leaning clock tower.

I worked at this place from 1981 to 1986, when it was still just a small town. Back then, the people were friendlier, knew each other well and looked out for one another. Perhaps, that is why I feel nostalgic whenever I talk about Teluk Intan.

Personal musings aside, today the place has progressed by leaps and bounds, and is gaining prominence as an ecotourism spot.

In August last year, my friends and I went to Pulau Bangau in Teluk Intan, a 6ha islet that is home to more than 30,000 birds of various species. Of course, the largest group of birds here are storks or "bangau"; currently, it's inhabited by more than 10 species of storks including the bangau besar, bangau batu, bangau bakau, bangau Cina, bangau kendi, bangau kerbau, bangau paya.

There are also little egret, cattle egret and meageret egrets, and eagles, too.

We took a boat trip down Sungai Perak for about an hour in the evening, just before sunset. The green vista, with various species of migratory birds hovering, kept us spellbound.

Some of these birds make a stop here after their airborne journey from as far as India and Thailand, and breed on the island. Pulau Bangau is an ideal habitat for breeding for two reasons: it is far enough away from humans, and there are plenty of food to be found here.

Each day, these birds start looking for food at about 5.30am in nearby areas that include Teluk Intan and Seberang Perak, before returning to their nest at around 6.30pm. Tourists can avail themselves to about 20 locations along Sungai Perak to watch these birds.

The sight of birds flying from one dwelling to another, resting on tree-tops against the backdrop of a picturesque sunset, are the reasons why tourists, locals and nature lovers keep visiting.

Besides observing these birds there are other attractions here too, like the furnace of a sunken steamship, shipyards, in-cage fish breeding farms and a Buddha statue. Each of these attractions have their own unique story and history to tell.

After a tour of the sights where migratory birds make their daily presence, we returned to the jetty for a short break. Then, we were off again in our boat for a short trip on the Sungai Perak in pitch darkness, to see the fireflies.

Firefly sightings happen all-year-round in Teluk Intan, provided the weather is good. The best time, however, is when the moon is at its smallest or faintest, and when it isn't windy. This is when you can see fireflies in their full glory.

Upon reaching the edge of the river, we saw some fireflies on the tree tops. These fireflies, also known as glow worms or lightning bugs, are bioluminescent insects, aptly called kelip-kelip in Bahasa Malaysia which means to flicker. We had a closer look at them from just a few feet away shortly after.

Our boat driver managed to collect a few fireflies in bottles for us to see them better. Due credit must be given to the driver who knew exactly where to find them in the dark, as fireflies are often found in areas enveloped in complete darkness.

What an enlightening and fulfilling holiday it was for my friends and I. Being in harmony with nature is a priceless gift bestowed to mankind. Schools should organise excursion trips to places like Pulau Bangau to educate our younger generation on Malaysia's flora and fauna.

Overshadowed for a long time by many other well-known places in the country, Teluk Intan is slowly carving a niche as an ecotourism destination in Malaysia.
