ASSESSMENT

What an assessment looks like.

Bring the observations together around your site. Understand what changed, what the evidence supports and what needs further attention.

Evidence

Site boundaries, indicator layers and changes across available observations.

Interpretation

A written assessment with the supporting data and its limitations.

Action

A basis for prioritising site reviews, monitoring and follow-up questions.

Demonstration assessmentEdited excerpt

How has vegetation changed at the site?

Vegetation & nature · NDVI · 102.2 ha, Kulai, Johor
8 captures, Nov 2021 to Aug 2026

Finding

Closed-canopy vegetation (mature oil palm) covered 96.6% of the site on 21 Nov 2021 (NDVI 0.88). By 14 Aug 2026 it covered 0.3% (NDVI 0.14). Bare and built surfaces and open water replaced it step by step.

Interpretation

Canopy was already down to 28% at the Aug 2023 groundbreaking, 13.8% when the first 8 MW went in (Jun 2024), and 3.5% when two further phases were announced (Feb 2025). The loss runs alongside the reported build timeline.

Coverage & limitations

Two captures cover 80.5% and 89.5% of the site, so those two rows describe the covered part only. Remaining green cannot be told apart from plantation regrowth by NDVI alone.

Question

How has vegetation changed at the site?

Answer

The site went from near-total closed-canopy vegetation (mature oil palm) in late 2021 to almost none by mid-2026, replaced progressively by bare and built surfaces and open water.

SOLUTIONS

One platform, seven ways to use it.

ENVIRONMENTPeatland fire & haze

Fire detection, burn scars and the haze outlook for a peatland site, shown in a platform demonstration.

What we seeLeft: fire detections (yellow dots) over Sumatra and the Malay Peninsula, on a gridded haze outlook that is strongest over southern Sumatra. Right: burn scars (orange) mapped on a Sentinel-2 image of an 85,268 ha monitored area, with burned-area totals for 2015, 2019 and 2023.

Burn scars, fire detections refreshed several times a day, and a five-day PM2.5 haze outlook over drained peatland.

INFRASTRUCTUREData centre impact

Assesses changes in built ground and vegetation around a campus across available observation dates.

What we seeLeft: built ground (blue) across a data centre campus and solar farm on 16 Apr 2026, with 35.7 ha built on the campus, beside a dated list of reported milestones. Right: a vegetation-change map (NDVI) with the cleared campus and solar farm outlined, and the surrounding ring compared against a control area.

How much ground a data centre campus has built on, date by date, and the vegetation it replaced. Evidence for NSRF / IFRS S2 climate disclosure.

ENERGYSolar farm asset monitoring

Compares aerial imagery with satellite change detection to show where a solar farm changed after a damaging event.

What we seeLeft: aerial photos of a solar plant from 2022 and August 2025, with the visible panel area falling from 13.7 ha to 12.1 ha (−11.8%), mostly in the north-east and west clusters. Right: a 10 m satellite change map over the same clusters, with a time series beneath.

ENERGYSolar construction progress

Compares changes in built ground across satellite observations with reported construction milestones.

What we seeLeft: a 716.1 ha array site on 26 May 2024, with 0.8% read as built ground and the rest farmland. Right: 15 Jul 2026, with the array footprint filled in blue; the panel notes that after November 2025 the footprint is set by the method, not measured.

LAND USEPlantation clearing

Tracks vegetation change over time across land being cleared for plantation.

What we seeTwo dates over the same 5,022.7 ha area. The share of ground below an NDVI of 0.4 rises from 8.4% on 5 Jul 2022 to 17.2% on 19 Jul 2024, shown as orange patches where cover has thinned. At the marked point the reading falls from 0.54 (shrub or young plantation) to 0.11 (sparse cover).

Five years of vegetation change across land being cleared for plantation.

OIL & GASMethane

Screens satellite methane concentrations to flag large potential sources for closer investigation. Screening alone does not establish a facility’s emission rate.

What we seeLeft: methane concentration on 5 Oct 2022, a baseline day, with a reading of 1931.4 ppb at the marked point. Right: 8 Oct 2022, with a plume flagged as bright patches near the coast and 1997.2 ppb at the same point.

URBANUrban heat & thermal sharpening

Shows observed surface temperature beside a modelled, sharpened view. The sharpened detail is estimated, not measured.

What we seeLeft: observed surface temperature at 70 m over Kuala Lumpur at dusk on 7 Jul 2025, in coarse blocks ranging from 27.4 to 34.3 °C. Right: the same scene sharpened by a model, showing road-level detail and warmer spots the coarse view blurs. The sharpened view is modelled and not validated against finer thermal data.

Site & purpose

About

Based in Malaysia, working across ASEAN

Celestara Sdn. Bhd. is a Malaysian Earth-intelligence company turning satellite imagery into site-level analysis for governments and organisations.

Malaysian university research collaboration

Celestara Sdn. Bhd. delivers a multi-indicator Earth intelligence platform across ASEAN and beyond, from a Malaysian base — combining international engineering with local delivery, institutional research collaboration, and long-term commitment to building capability in the region.

Heat, vegetation, water and emissions are assessed in the context of a site, with written assessments that help organisations review change and decide what to investigate next.

Differentiator

The decision layer, not the pixels

Imagery is increasingly a commodity. Celestara's value is the cross-indicator analysis on top of it — heat, vegetation, water and solar assessed together on one polygon, with a written analysis, not a raster to interpret yourself.

Regional delivery

Malaysian roots, ASEAN reach

Celestara is a Malaysian company working across ASEAN: local contracting and support, research collaboration with a leading Malaysian university, and deployments designed around each country's regulatory and data requirements.

Start with one asset.

A 30-minute discovery call, a pilot scoped around a single site, and a clear proposal. That's how every engagement begins.
